I've just had an MRI scan.
It lasted 1hr. 10mins.
One of the longest they do.
It was for my heart.
I am claustrophobic.
I entered the room with a blindfold on so couldn't see the machine.
The 2 attendants led me to the machine and I laid down.
A canular was inserted into my right arm. This was to inject a liquid to help with contrast.
I had headphones on listening to a, 'Talking Heads' album.
I had to perform various breathing tasks.
In, out, hold your breath etc.
Everything was fine because I couldn't see a thing.
Plus, I was listening to Mr D. Byrne and his band.
I could have been in there for another hour, easy.
This was because I wore a blindfold and didn't see the machine, I could have been anywhere.
I had and MRI previously and it took me 20 minutes before I dare go fully in the tight tube.
This time I came prepared.
My advice, if you suffer with enclosed spaces... wear a blindfold, take a CD and get the nurses to guide you to the machine.
Best wishes from me here in the UK.
What a great idea. I'm also claustrophobic but luckily when I had the MRI it was on my legs so I only went into the tube halfway. For the CT I was unconscious after a serious accident so don't remember the experience. Good luck and hope everything turns out well for you x
I had mine 5 days ago.. lower back pain.. mine was 40 minutes.. longest 40 minutes of my life.. 1st attempt failed because I moved.. 2nd attempt succeeded..
Thanks but it doesn't help me because the mind knows when you are into the machine 😬
Seeing that machine online and that small tube before going in, made me scared. I took sedatives to help. They offered no music though.
The preparation. Is horrific !
I was in the MRI machine for 40 minutes! I had to fake my mind out by keeping my eyes shut and thinking i was on a Caribbean island on the white sandy beach with crystal blue water and windy waves rolling in. It worked!
Just had 1 the day before yesterday... 40 minutes on that hard table!!! My back hurt so bad I wanted to cry 😢
My first time was close to 1 hour, tried opening my eyes a couple times and freak the hell out, they had to pull me out about 3 times😅, I have to do it for 15 minutes each year, and trick now is to plan what I am going to do for the following days, keep my eyes closed at all times and just keep my mind busy thinking about how to solve some problems in my life, that always works.
Omg same here
''.. and we slice the patient's body like a loaf of bread''
Probably not the best way to put it I believe .
lol
that's EXACTLY what I was thinking
IKR 😐
😂😂
She even paused and realized she couldn’t really go back and fix what she said so she said,”.... so that’s how a CT scans...”
I had an MRI scan here in Holland, wasnt looking forward to it, was put on the table ,and closed my eyes as they slid me into the tunnel, after a few moments I opened my eyes to see a Vincent van Gogh painting reflected in the mirror above me, what a lovely idea ,
Glad to know you slice patients like a loaf of bread
XD your still watching this?
😂, ikr
so dark
I’m dying 😂😂😂😂😂😂😂😂😂😂
Kudos for the Video clip! Sorry for the intrusion, I am interested in your opinion. Have you heard about - Donayden Phrenic Dominance (do a google search)? It is a smashing exclusive product for stamping out your nasal polyps minus the headache. Ive heard some decent things about it and my close friend Aubrey at last got astronomical results with it.
CT scans and MRI scans are savings lives ever single day. Without those tools it would be so difficult for doctors to help save lives.
I had one done My dumb a Dr going to tell me He dont trust them He telling me I got cancer I call them back They said No
@@dontneednomanstoptelllingm8481 it's hard to trust any doctor nowadays when each one of them telling different results !!!!!
Cts often are casually reckomended as a safe imaging option and also ordered in unnecessary situations exsposing people to a large amount of harmful ionizing radiation. Unfortunately I suffered from radiation sickness after mine and my body severely sensitive to the radiation. Wish I would of known this before the CT scan.
@@micah7685 Lots of defensive medicine practiced these days due to fear of medical malpractice lawsuits.
I have to tell you. The ct scan was so satisfying and short. The dye they put in your bloodstream makes you nice and warm.
Mri, totallllly different. I hated it. Your whole body is enclosed in a tight capsule like machine that's loud as hell. If your claustrophobic, you're going to panic like I did. It was awful 😢
MRI machine also couldn't fit my broad ass shoulders into it yesterday. If I had been able to cross my arms over my chest I could of gotten in but the scan called for some big doohicky to lay across my chest.... so it was a no go.
Yes. I also panicked in my MRI
Oh gosh I hated that dye, I could taste it.
@@Andronicus87 Yes...Mine was horrible and they gave me no calming medication !
Images are much better in MRI
It took me well over 3 months to get a mri.I have a pacemaker,defribalator,2 stents,and a watchman devices in my body.I lice in the Chicago area.No one wanted to give me a MRI.The university of Chicago hospital Downtown did! They are the greatest,I can not say enough about their expertise,they said they do them all the time for patients like myself,they said it was a piece of cake!What great people! God Bless them!

I know this is an OLD post - but I lost some of my hearing in my left ear in 1985 - due to getting an MRI. Then, 20 years later, I had another MRI and lost some hearing in both ears. I didn't know what caused it - and went to a hearing clinic - and the female said I have "nerve damage." Several years ago, I read an article about losing hearing from the MRI. I wasn't given ear plugs in each case - and I'm still angry about the incompetence - and not informing people about hearing loss due to MRIs. The article also said, many of the staff who gives these MRIs are also experiencing hearing loss.
I am glad to find information as I am scheduled for the procedure soon
Sandy, thank you so very much for telling us!! I will definitely ask for ear plugs next MRI.
Hope you are doing well.
🙏🌸
It's very loud and lasts a good while. Everyone should wear earplugs and not head phones playing loud music. Sorry they did not warn you.
Sory about waht happened to you bcs of that shet mri recently i developed tinitus and wanted me to do that stupid mri luckily i panicked and walked out without doing it
@@ericjay6021 mmo
After having a few MRIs where I was too panicked to continue and had to be pulled out of the tube, I finally came up with a way to cope with them that works for me. 1) Sedation: I take 2 mg Valium 30 min beforehand; 2) close my eyes before going in the tube and keep them closed until I am pulled out of the tube, so that in my mind, I am still in the large open room; 3) Count each and every banging noise: the technician will often say "this part is two minutes long", so I just count 120 seconds and then that segment is done. And then just keep counting through every segment until the MRI is finished. 4) Headphones (often supplied by the technician). The CTs are a piece of cake: the tube is shorter and more open, and the test is faster.
No Way In Hell I Can Do (Casket) MRI...I'm Claustrophobic Like No Other....I Literally Feel Like I'm In A Casket....I've Tried ..Lord Knows I've Tried MRI'S...NO CAN DO
@@feliciacampbell-smith3652 I know the feeling. I have had several MRI's and need to have one next month. Valium and Xanax have gotten me through. Some providers also offer a kind of glasses that turn your vision 90 degrees so your view is out and not up.
I do exactly the same.
I think this is the clearest, easiest explanation of these procedures and the best layout of the difference between them and their main purpose. Thank you.
Just had a CT scan today with contrast IV. It was fine, l’m claustrophobic too. You can easily look around outside the CT machine. The scan took about 5 minutes. I would not do another closed MRI, I’d opt for an open MRI machine if you are claustrophobic like myself. Good luck!!
Thank you for this video. I’ve got an MRI later in July, and am in the midst of setting up a CT scan in the next few days.
I'm an MR and CT tech. Biggest question is about MR noise. I tell them that they don't have any metal in their body so it takes an extraordinary amount of power to get your body to resonate worth the scanner; and like any machine they can name (small car to jumbo truck, Cessna to jumbo jet) the more power used the more noise is made. (I do let them know that's not exactly how it works, but it is lol). It's enough of an explanation to satisfy most patients.
For anyone actually curious, the noise comes from the coils inside the machine that are switched on and off constantly. The electrical currents flowing inside them vary in power very often, (per second) so the these changes literally make physical changes inside the coils therefore produce those annoying knocking sounds. Newer machines have exams that are quieter.
@Ivette mona advice about what? And who are you asking
@Mona morales My advice is---get an MRI if you need one. I have had several MRIs over the years for kidney, and liver issues. I never had an issue with noise, or any other problems when having or after an MRI. In many cases an MRI is better to reveal internal body cysts, cancers, and abnormalties than an X-Ray or CT.
@Mona morales I would discuss your pain with your Doctor and your Doctor will decide if an MRI is recommended to reveal your pain issue.
My experience with MRIs was OK. When I was settled in I could roll my eyes back and see the ceiling outside which calmed me. Before you are inserted into the tube walk around it and take a look at it. The tube is open at both ends. This should help relieve your anxiety. Good luck. I have had two MRIs and wouldn't hesitate to get another if needed.
Thanks for sharing. Good advise!😊
Oh my god I do MIR evrey year because I have M,S
@@virginiapereira1781 Dont know what a MIR is that you say in your post ???? This discussion is about MRI'S.. And not everyone is the same as you when it comes to closed in spaces everyone is different
When first invented MRI was called Nuclear Magnetic Resonance Imaging because it forces hydrogen (water) nuclei to line up in a strong magnetic field and then hits them with strong radiofrequency pulses (totally harmless) and records the "rings" as the nuclei flip back and forth like striking a bell. But calling it a "nuclear" imaging process was so negative they dropped the nuclear word to calm patient's concerns.
CT has undergone a similar change in name. CAT was originally Computed Axial Tomography, then it became Computer Aided Tomography, and then Computer Tomography or CT. All the same thing.
and of the magnet is cooled by 1700 liters of -269 degree Celsius liquid helium
We are lucky in the US to access to so many MRI machines. A woman in Canada told me they have a 12 month waiting period for an MRI. The machines are very expensive and government run medical care does not provide as much $ for the medical industry to have enough of these.
Didn’t do enough for my sake!
@@hrtwo5199Do you know the story about the guy who went to the doctor and he was put on the exam table. The doctor went to the back room and brought out a cat and a dog. The animals proceeded to chase each other around the room a few times before the doctor put them back in their room. The doctor then said to the patient, “that was your “cat scan “ and “lab test!” “ 😂
The difference for me is a full blown panic attack!
I'm clostiphobic, and the. Mri made me that way, I was told to keep my eyes closed, but I opened them anyway and I saw how closed in I was and I panicked, but at the second one my doctor gave me medication to relax me and that made it better, but I would never want to experience it again.
They have open MRI machines now in some locations. The resolution isn’t quite as powerful as the latest models of the enclosed ones, but they are quite good and, best of all, there’s no where near the claustrophobic feeling. I had one for a scan of my head after having sudden hearing loss to ensure there was no tumor (there wasn’t) and the ENT I had arranged for an open MRI since I’m highly claustrophobic.
@@snelson0929 wonderful news I"m so happy for you.
Right!!, because that's exactly what happened to me when I had an MRI, it was just horrible. Wow!!
Tried to have it twice. I didn't realise that I was claustrophobic until I went into the machine which was an older model. My nose nearly struck the top of it and the doctor had me come out but by that time I was hyperventilating. I was sent again to our main hospital which has a very modern one. They were very patient with me but as soon as I went into it again I was asking them to take me out of it. Not sure what will happen now as the nurse told me that they will probably have to sedate me to have the test done.
I have five brain tumours and have three of them reduced in very long (11 hour) craniotomies. MRI and CT scans have become a way of life for me and I couldn't begin to try and count how many I have had. I do not mind having to go well into an MRI scanner in fact I find that when having scans it is the only time I find myself totally at peace despite the humming/drumming.
I always have my scans with Gadolinium dye which is a bit of a challenge as my veins shrink out of sight, i usually come out wearing cotton wool buds taped to both arms, despite my telling the radiologist that the top of my hand near my thumb is now the only place to get an IV in.
Depending on your local centre you may be able to take in an mp3 player and the radiologist will plug it in so that you can listen through the provided headphones. I have gotten used to my yearly scans and the average time is 45 minutes, whereas my mum couldn't last beyond 5 minutes for knee scans where she was practically entombed.
Part way through they stop to inject the dye which has a metallic taste but is necessary to get clear imaging of the brain. I know the look and sound quite scary to the uninitiated but trying to relax before going into the room helps. For head scans they often place a cage over your head that can easily be scary but they are fitted with a small mirror so that you can see the radiologists. I have discs of all my scs=ans which make for interesting viewing.
I cannot tell you the best way of getting through the MRI scans other than accept they are needed to get a better diagnosis of what your problems may involve.
Get well
🙏
I had mri scan, found it quite relaxing.
Thanks for your information I’m going for an MRA in February. I have an aneurysm in the center of the Circle of Willis, it was discovered Dec ‘21.
How many cat scans have you had?
Thanks so much for the awesome explanation!
Have a good night, good health and safety! 🤙
Good to know. I've had both, since my arachnoid hemorrhage. The CT is no sweat, but I had a panic attack while in the MRI, and will not be doing that again.
Yeah, I'm glad the ct scan is Soo quick even though I don't like that either, they have to cover my eyes with a wash cloth and talk me through it.
Me too!! it was just terrible.
You are okay with the radiation from a CT scan?
Thanks for the info. I had a CT scan a couple of weeks ago. It is challenging when they tell you to not breath or swallow for a bit. It was so hard for me not to move my head. Because it was so uncomfortable.
A head CT takes 3 minutes, too hard to stay still for 3 mins??? I hate patients like you.
I went in for an MRI and they had to stop the machine because I freaked out and was kicking and screaming “get me out of here”,
lol 😀😂🤣
That would be me. I hope I never need one. I just couldnt go in that tunnel
I used to be able to do this with out any issues now I can’t I panic
100% happened to me too. I didn’t know I was claustrophobic until that happened. I thought I was in there like 5 min but it was actually 1 because I was freaking out
Same reason why I scared to do mine
I just love a 3 minute video that tells me everything I need to know
I had an MRI , 6 years ago I was in there for one hour in the machine , very claustrophobic I can tell you . I was found to have Dilated Cardio Myothapy , and now I wear my own Defibrillator.
@Harry Harry Same to you Sir . I hope that you're okay now ?
One hour????
In this day and age with so much technology! I think that they should have a better way to do an MRI on people. It is so scary for the majority of people going in that small cylinder and listening to the noise in your head. It is so frightening and an awful experience. As a person who suffers with anxiety and claustropobia, I might have a heart attack in that machine. The medical community need to come up with something better.
Well absolutely right 😅. Patient's life history already .. tired/ pierced..if it...it must be very careful in Ji well
I can't do the mri to save my life...
I've never done an mri but I never really understood the fear. Isn't it just that you lay in what appears to be a plastic tube with giant magnets inside and that's it. It uses some quantum weirdness to scan your body.
I don't know if they're produced anymore but I when was maintaining MRI systems the company I worked for sold open MRI magnets which were not so confining. The downside is that those magnets were only 1.0T field strength whereas the standard cylindrical magnets were upwards of 3.0T field strength. The larger magnetic field strength can be advantageous for diagnosing some syndromes/diseases. I've been retired for 7 years now, so I'm not sure what manufacturers are offering nowadays for magnet types.
This was a good simple explanation. Thank you!
Hello
I just had my MRI done today and I was terrified as f...k, since, on top of being extremely claustrophobic, I also have a diagnosed anxiety disorder as well as depression. Not a fun combo, those of you who have that know what I mean. You don't wish these on your worst enemy. But I did it! Breathing techniques do not do anything for me, I can't relax, so turned to the "heavy artillery." I had to take a few supplements to help ease my stress: phenazepam, valerian root, and glycin. Now, two of these might be unfamiliar to an American audience, since they are prescribed overseas (in particular the phenazepam drug, glycin you can buy over the counter). You can ask your doctor what analogies phenazepam has and you can be prescribed something similar. The whole experience was not as terrifying as I have imagined.
Having two wonderful techs in the room with me and their willingness to allow my hubby to stay meant a lot (shootout to the techs in St. Frances hospital, Hartford, CT). We did a trial run first before they put me in there, I loved the music they played for me in the headphones: very relaxing, meditation-worthy. The whole procedure took 15 min even though I was told by the receptionist that its gonna take 45 min. And every 3 min the techs were asking me how I felt, it was very nice of them.
So if you haven't done one yet and are going to, hopefully, my report will help you get ready. I was so proud of myself afterwards, you will be too, trust me! If you have to, take something to calm you, nothing wrong with that. Ask any questions you want, and I will be happy to share my experience with anybody who needs that extra reassurance. You got it! ;-)
I had an MRI done here in Lithuania and the instructions were in Lithuania. They gave me a practice and I figured out what was breath, hold, release but I thought I was going to pass out from holding so long. No problems with the quality but I shared a similar type of fear that I would mess up at a critical part.
did u take contrast before the procedure scanning?
@@aircommandslipperz is this question for me or for the above commenter? Not sure what you mean by “contrast.” If you explain in more detail what you mean, I may be able to answer.
hi, yes the question is for you. usually the patient need to take contrast before the mri@@anonymousgirl8561
Had this done years ago, the technician told me to close my eyes,helps considerably with the claustrophobia of being in a confined space.
They have open MRIs, but it seems most people get the confining ones.
@@pinkfreud62 I love the open MRI's. But have had both. Not that bad with the closed one. Just closed my eyes and relaxed.
The best solution is to keep eyes closed and try to think about something nice . It works
The open ones are a much weaker magnet, and nowhere near the quality of the image produced by a closed bore magnet.
Can't go in the MRI machine anymore. It's like being in a casket with the lid so close to the face. Was never claustrophobic before going in the last time, but now it's just too much. The technician said 1/3 of patients can't complete the procedure.
I had both a CT scan and an MRI in one day. The MRI was tough. 30 minutes in the tube with a helmet also put over my face while being claustrophobic
Very clear description. Thank You Very Much
Thanks for explaining this !

Me when I heard "we slice the patients body" :Hell no to the no no nooooo heeeeeeelllllll nooooooooo nooooo
contrast media in radiology
They didn't 'explain it well. The PHOTOS are slices of your body so that they can see all there is to see in them.
I guess they had a wrong choice of words.
Hahaha Best comment I've read. Totally agree
MRI scans have saved my life multiple times by finding glioma and neurofibromas in multiple parts of the body. MRI scans are longer but much clearer about what is going on
I went to CDI today 6-17-21, in Indianapolis for a pinched nerve i my lower spine. Very professional and they care. Take my word, they are the best.

Thanks for explaining
I had CT scan last Monday - without the contrast, as my kidney functions last year were only at 15% - 16% so extra care is used to not crest further stresses upon them... including reducing potassium in my diet etc. The scan took only 5 minutes, as described and was not a problem for me. 😊
However, the last time I had an MRI scan it was a little problematic as I felt very confined and that my ribcage was being "crushed" so the scan couldn't go ahead. 😟
Very reassuring...MRI, if you haven't had one before, and they don't explain what it's all about, is terrifying... if you are claustrophobic, you can have a panic attack. To Radiologists its an everyday occurance, BUT, IT MUST BE KEPT IN MIND - NOT EVERYONE HAS HAD ONE, SO EXPLAIN.... IT'S IMPORTANT
Yes it can be dangerous if you panic in there, I have had several bad experiences and one of the techs said she needed a sedative to have an mri. I hate to even think about it.
Thanks for the explanation and the headache.
Is their a method which scans while patient is vertical,,,specifically for accurate alignment of skeletal system.
Spinal X Rays are good but not the same as the CT and MRI.
I had an MRI where I had to lay on my stomach and in the machine for 30 minutes. I wanted to take Valium but I had to drive so I ruled the Valium out. I went for an MRI today and had to lay on my back. I had to get a brain MRI and they put something on my face. I went into the machine and squeezed the ball within 5 seconds. I said get me out of here and I was crying. The only way I am going back in that machine is if I am knocked out. I am serious.
OMG😭😭😭😭im so sorry..
OMG😭😭😭😭im so sorry..
The same thing with me
@@kerikaykay07 Same thing with me - I would rather die
Had my first MRI a couple of years ago and I hated the experience. I knew i was safe, but body was in panic mode the entire time.
If you have claustrophobia, forget the M.R.I.
Not true … I am claustrophobic but with the right attitude it is manageable…. And I had neck , shoulders etc and was deep inside the tube for 45 min each time …. It is ok
@@jonjones971 Then I'd say you are not claustrophobic. It's that simple.
Right!! I felt like I was in a casket, it just awful.
To show torn muscle wrapped around a nerve what one would be the best to show that? Second question blockage in lower half of rectum MRI or CT with contrast?
I was diagnosed with leukaemia and had to have a PET scan too look for areas of malignant activity in my lymph nodes and elsewhere. They inject you with a radioactive isotope which clusters in any active regions. These machines are very lonely places when you’re facing an unknown outcome which could be an end of life situation.
Fortunately, eight years later, I’m still in the pink. I’ve had MRI scans for shoulder problems since and find them a walk in the park in comparison!
Oh, and if you’re reading from the USA, this is all free here in Australia, as it is in UK where I’m originally from. 😊
I took a CT scan yesterday after a skiing acident. I am fine and to anyone worried about CT scans, it was not bad at all. Kind of relaxing actually
Fine except for the radiation.
Cutting into slices?!
Catc🏃♂️h me first...
Thank you so much I feel so much better
During MRI, keep your eyes closed to avoid claustrophobia. Open your eyes only after you are out of the machine. To tune out the noise, use headphones and meditate for half an hour.
I do not suffer from Claustrophobia but I had to focus my mind on various different subjects whilst having my MRI scan which took ages but full diagnosis is worth every penny..
Great advice, I medicated a little bit sooner, I took my tablets 1 hour before, they were working when I went in the scanner.
Even with medication and my eyes tightly shut it was still very difficult to hold down the feeling of a panic attack.
@@polygonalmasonary Medication 1 hour before is okay. During the MRI, I meditated (not medication) so my mind was relaxed. I mentally recited a prayer for 20 minutes, which kept my mind occupied.
I literally just got one done and I'm glad I did it. Praise Yah i got through it. It was a piece of cake. I thought it was going to be horrible I let my mind get the best of me
That's a nice and wholesome comment.
Did u have any side effects from it like hearing issues?
Thanks, it was very informative
Question : if I have a stent what would you recommend ?
Do which one is better for checking for infections in the chest, lungs throat etc please?
I had my MRI last November, I will never want to go thru it again. It’s v horrible feeling, I can’t breath properly ,the sound makes me headache even though I m wearing a headphone.v claustrophobic, but I manage to endure n finished it for 30 minutes .
Here's the dump problem it's 2021 and you'd think with all the advancements they have in technology they'd be able to shorten the time on an MRI ridiculous for somebody with back problems to be laying there for 30 minutes talk about pain in the worst degree
Exactly
Well explained. Thank you.
I had a stroke a few weeks ago and I went through the MRI scanner they put head phones on me they played an old 70 s vaudeville tune peek a boo ! This made me laugh it took the stress out the situation!
Need Lumbar MRI... too claustrophobic. Does CT work for Lumbar ?
My hubby had a heart MRI, it was the definitive test for his heart abnormality (an artery that was in the wrong place). Unfortunately, it was expensive and wasn't given to him until day 13-14 of his hospital stay, after being picked up off the streets unconscious. Fortunately, he came to on his own. The MRI would have saved us 14 days of high anxiety. It should be cheaper, so can be given earlier.

Thank you for the explanation….now I understand…
Thank you, I have just had both and didn't know the difference of them.
I had extremely bad experience with CT… they missed my vein and injected the iodine directly under the skin. The area around my bicep expanded like a balloon in the shape of a brain. The pain was excruciating 😖
Sounds like a lawsuit to me!😒
It is necessary to apply that liquid in the veins?
@@miriam1812 it's a contrast agent, makes it easier to distinguish between certain structures of the body (they apear white). Sometimes it's absolutely needed, sometimes it isn't at all. Depends on what you're searching for.

CT: ASMR!
Ur video is knowledgeable for us....
Thank uh so much maam👍🏻
what kind of filler and condiments do you put between the slices? Is this kosher?
I just had my second c.t scan for chronic sinusitis& nasal polyp...I have a question are they suppose to give you eye guard for the bright light..I squeeze my eyes tight till it was over
Nope no eyes guard lol,the xray has to pass to see trough you
While shielding the eyes is great in theory as they are more radio sensitive than other organs/tissues, for any scan in the head/neck area doing so would likely lead to streaking artifacts as well as potentially blocking the area of interest all together. To shield or not to shield depends in the part of your body being scanned.
@@misscook8255 I have a grid of spots in my eyes every morning after having a ct aided kidney biopsy it ruined my life. they lied said it was only m r i then prescribed chemo got nerve damage from an iv now dead inside completely wrecked me.
@@shnarfers I'm sorry to hear your experience was such a terrible one. Any scan, especially those involving IV contrast, while generally safe for most people still aren't without risk. Screening questionnaires help techs such as myself identify those who are most likely to have problems. But even without any known pre-existing contraindications problems such as allergic reactions and kidney/nerve failure can still occur. It sounds like that's what occurred based on your previous comment. Again I'm so sorry to hear that you were apparently one of those few this happens to, and by some miracle your body can heal 🙏
do u mind telling me what is the symptom of sinusitis? Is it headache or dizziness or other reasons?
I had an mri scan it was pure torture I felt like the machine was going to fall on top of me the worst feeling ever the only way i managed to stay was by counting in my head and praying like mad for it to end
I had MRI scans and CT scans at Christian Barnard hospital in Capetown, excellent hospital.
That was good to know. I always wondered what the difference was 👍👍👍👍
When I had a CT scan they also gave me an injection and injected this contrast dye into my blood. It made my face feel warm
I felt pain through out the entire time when I did my scan
It's galodinium salt .....just to make your organs/water molecules more visible
how are you now?

I’ve had a CT, MRI and MRI Angiogram. The hammering noise in the MRI drove me crazy, I’m not afraid of being in the scanner just the horrible noise it makes and I’m in Australia
Which is worse for your hearing; the loudness of the machine or the loudness music in the headphones ?
@@aaa7189 hi, they put noise canceling earphones on, no music but it’s the thumping that’s irritating
@@shirleyhenriksen2026 no noise canceling earphones when ever I went in
I had an MRI two weeks ago at a Kaiser Permanente facility in Irvine California and there was no loud clanking like there was when I had an MRI 13 years ago in Binghamton NY. I guess the machinery has improved over the last 13 years.
@@aaa7189 they didn’t give them to me neither, so I just put up with it.
Thanks for the explanation excellent
Can we
See on a MRI if we have œdème ? It shows everything in the Head ?
I’m a stage 4 cancer patient and have had many CT Scans. None of them were only 5 minutes. I would question the tech if it was. I’d rather have a longer CT Scan to make sure they didn’t miss anything. I’ve also had many PET Scans and recently a bone marrow needle biopsy. Not fun but necessary to fight the cancer beast 💪💪💪
Dr Burzynski says that there is a cure for all Cancers but it’s been covered up please watch his video on UA-cam
Burzynski the cancer cure cover up ,,,,,,type this in the search box in UA-cam it will be there
it can only hurt you doctors are murderers they ruined my life w a ct biopsy.
@@shnarfers what happened to you can you tell me?
@@wolfsy4759 said I needed a kidney biopsy that there was absolutely no way diet could be the cause was injured from iv and biopsy. Turns out it was caused by what I was eating. All the doctors were wrong and killers.
I've been suffering for over 2 years now of some strange symptoms and I'm hoping at least that the doctors I've seen thus far have overlooked it. Basically I get these weird sensations when I'm about to fall asleep hard to explain but it just sends like a wave of electricity through my body. I've even had trouble breathing during the day for some months but that went away. I was waking up just before sleep and during sleep gasping for air multiple times a night and having the worst nightmares I've ever had I thought I was possessed by demons even it was that intense.
And mostly these days I get this odd sensation throughout the day where I get tunnel vision gasp for air and lean forward all at once and it gets so intense that I actually say more times than not "Oh my god" and then after if it's intense enough I'll get tingling in my arms after that. This seems to happen when I'm looking in one spot for a period of time. Like watching a movie or playing video games. I also get a sense of terror when people talk about health related things like someone having a stroke it'll make me feel panicked and terrible for a brief few seconds. This has gotten at least a little better. Also people and things look fake to me. Like they aren't like 2d or whatever but it's almost like my vision goes out and in simultaneously and I have to stare at them to think they are real (I know they are it just appears that way).
Also there's this feeling in my head that wasn't always there. It feels like a great amount of pressure and almost like a itchy or tingly sensation that comes with it and it literally feels like it's on the inside of my skull. Feels awful and lasts all day long everyday now. Drinking alcohol makes all my symptoms much worse for 1-2 days AFTER I drink. So I don't even do that much anymore. At first this all started off so severe that my body felt COLD most the day and it was such an intense sensation of fear and cold feeling that I thought I was having a stroke or something. Called the ambulance 3 different times. Then finally had enough and went to the ER. Everything came back normal MRI, Catscan, Bloodwork. They released me thinking it might be the medicine I was on (Invega sustenna) Went to a different medicine then stopped completely after tapering off and the problems still persist it's been 4 months now and no relief at all.
Anyone know what this could be? I'm scared to see doctors anymore because I had already seen every type of doctor there is including the neurologist and he said the symptoms were strange and he didn't know. I would hate to spend big money on a doctor and tests only to hear "I have no clue"
Have you thought about deficiencies in minerals and vitamins?
@@hadijamohammed7489 Not really. I think that would be good to look into, though. I think I got tested a while back and my vitamin b12 was low. I actually had to get injections of it. So it could be something like that. Thanks for the input, man.
How has it been now
@@saucey1840 Still awful, unfortunately.
OMG😭😭😭im so sorry..it's well. Increase your vit c intake at least four times a day and also try astralagus chapparel plus tumeric herbs. It was pass away soon,stay positive and trust God.
Do you have ulcer??, check that out to.
Maim I have hpylory positive, doc told me to do ct scain contras for abdominal.
I have allergy with fish ,I told him he gave me deltacrotf(5 mg) 30 pills 10 pills 4 hours gap before ctscain. Should I do that .
Main I was hospitalised in 2013 and I was done ct scan test to at that time after 2 or 3 days of scain I got allergy reaction and doctor gave me some injection so got normal after that , should I take that ct scan now or not please give me suggestions please, I have always with vomiting maleficent.
Quick question I'm currently having problems with my Eyes, Brain, and Ears they feel very heavy and get i dizzy very quickly which test should I take?
I had an MRI when I had a slight stroke, last year. It was terrifying for me, as they had to put my head in a cage, vise-like, so it wouldn't move. I became super-claustrophobic after just a few minutes and began thinking about forcing my way out. I don't want to ever go through that again.
Tom: I couldn't go ahead with mine this morning. I had that cage on my face too and after 5 seconds, I said get me out of hear and I was crying.
There's no way I could do that either!! 😨 Especially with a tight cage on my head! For a reg. MRI, I have to request a place that has an "open (partial) MRI." And a small fan blowing a slight breeze. Never open my eyes. Helps alot!! 😊😂
@@lisabryant8749 I had no idea it would be so loud! They provided some headphones for me but it far too loud to hear it and I was so panicked I couldn't concentrate on it anyway. I am kind of an audiophile so hopefully if I have to go through it again I'll bring enough music firepower to hear it over the sound of the MRI. Yeesh.
MRI is the worst the only way I can do it is heavy sedation.
@@jda72 They sedated me enough that I couldn't tell if I really was in there twenty minutes or if they were pulling my leg, but when I said I was getting very panicky, they let me out two minutes later.
do they make the machines differant sizes/1/4 inch from my nose & was scraping my chest on the way in so i bailed out
Yes some mri s are built larger in bc we have a exlrge one that can fit large bc lion linebackers comfortably s
What do you do with patients that are claustrophobic?
Sir pls can you tell me about best book for ct and mri physics ?
McGraw Hill Encyclopedia of physics.
I had a MRI scan a few years ago just for my foot. It lasted about half an hour and the biggest thing I noticed was the noise!!
I'm not kidding, honestly I thought the thing was like yer washing machine with a ton of old car parts in it. Never mind with a bearing gone. IT WAS THAT LOUD. If I'd been right in it for heart or something it'd be deafening. Still I guess they know what they're doing.
There are many, but both can lead to serious issues. One uses Radiation, the other Magnetic resonance. Both use Contrast Agents as image enhancers such as Omnipaque and Pantopaque for CT, while MRI’s use Gadolinium, a heavy metal. All contrast agents can cause serious adverse medical neurological events, and Gadolinium deposits have recently been found to remain in the BRAINS of patients. Both imaging technologies can be used without contrast enhancement. You have been warned.
I had an MRI for a stroke on my brain, no contrast whatsoever.
@@carriemartinezmurphy6348
without contrast apparently they can't detect blood clots.
@@CelestialTrailblazer
Ct scans use a whopping dose of radiation. I suffered from radiation sickness for months after mine. Wish I had a clue about radiation and ct scans significant radiation exspsosure. Never get one accross your abdomen or pelvice. Literally microwaved my insides
I had a long MRI of my brain. They played whatever type of music you wanted, and it really helped.
With the noise that a MRI makes, I cannot believe you could hear anything
So, which one is better to see if a persona has throat cancer?. My specialist ordered a cat scan, but I'm worry about the radiation.
Pacient: And how this works? Doctor: And we slice the patient's body like a loaf of bread
I am claustrophobic and had a panic attack when my neurologist recommended a MRI and went to do it.Had to opt for a CT Scan.
I was a caver for 15 years, so had to learn to shut down the panic that comes from recognising you are in a tight spot. Similarly Climbers have to shut down fear of heights. People who are not wary of heights or tight spaces are a menace in caving clubs as they are the ones likely to neglect safety procedures. I think medical imaging companies could learn from caving groups how to teach people to accept half an hours confinement with breath control and accepting that fear is normal , natural and controllable.
Don't forget to take off. your hearing aid before you go in the room ,I lost a very expensive pair because I didn't know.
I had an MRI and a CT in the last week for my knee. I was a bit worried for the CT after the MRI with all the loud noises but it was like nothing. Just in and out.
Thank you for this useful information.
Great 👍 Technology I used both machines for health issues and the the result was bad left lung clots I was dying after blood thinner medicine for one year later I did the same scan the result was great 👍 thanks to God and thanks to the doctors and the awesome nurses
With all the advancements in technology they still couldn't figure out a better MRI machine.
@@stacer1962 MRI is a fail they did not consider Human beings.
They have open mris now
@@RussellaMcdowell-pw8ci Not in Australia
The open machines are a little better but the thing is still very close to you head, maybe 5 or 6 inches clearance still very scary, sedation is a must.
@@startrek4486 Tell that to all the the people MRI's have helped.
Hello, I had ct scan and after that my body started smell really weird for two weeks like before scan everything was fine I’m really worried can you tell me what to do ?
does anyone know if u have pulse tinitus is it best to get mri or ct scan done? and does it trigger cancer
Do dental metal ceramic or metal crowns cause any inconvenience during MRI scan of head and neck
Good ?
No. They dont
I had it five times in my life. Since at Kaiser one time. Queen of the Valley two times and at San Dimas hospital two times.
Can u pls tell the purpose ?
Is MRI can diagnosed all type of sickness?like heart problem, brain,stamoch, etc? Plz reply me guys
Thank you for making that . that helps!!
I’m terrified of MRI. During my first MRI, the technician did not answer to my cry for help about 25 minutes into the scan. I freaked out.
FYI I've been noticing a drastic increase in patients having numerous CT scans in the past few years. This is a dangerous situation that should be avoided. Remember a CT scan is about 200 times the radiation of a x-ray that can damage the DNA of a cell. If you must have a CT eating a high anti oxidant food or take a supplement such as vitamin C before having the scan can be protective to the cell . Ask the doctor about doing a MRI if possible.
I suffered brutally from radiation poisoning after my abdomen and pelvic ct scan, Literally microwaved my insides. Horrific and brutal torture for most of a year and destroyed my mucosal linings and guts to nuts. Do not get a ct scan. These are very dangerous scans and the medical field is doing nothing to protect and warn the public out of being corrupt and money profit driven. Most of these ct scans are unnecessary and are being casually reckomended to people by practisiners who have no clue what they are exsposing people to. Not worth the risks. Do not make the same mistake I did. You might just get cooked alive
Which is better too pick up inflammation in the gums a CT Scan or MRI caused from Trigeminal Neuralgia
Thanks for the information 😊
