I wanted to make this quick video about CT scans vs MRI scans. How do these scans differ? CT is short for computerized tomography, and MRI is short for magnetic resonance imaging.
Here is the biggest difference between the two:
• CT scans use X-ray radiation but are much faster than MRIs.
• MRI scans use radio waves and magnets to create a very detailed image.
MRI scans are great for taking images of:
• Joints • Brain tissue
• Breast tissue
• Blood vessels
• Discs
• Organs
• Torn ligaments
CT scans are great for taking images of:
• Bone fractures
• Tumors
• Cancer
• Internal bleeding
Problems with getting CT scans:
• The amount of radiation that a single scan exposes you to is equivalent to 200 chest X-rays. •
You often need to go back for subsequent scans, which exposes you to even more radiation.
• Too much radiation can cause damage to your DNA. When talking about CT scans vs MRI scans, you can see that MRIs are the best way to go.
However, there are certain situations where only a CT scan will work. In that case, I recommend doing three things to help offset the effects of the radiation on the body:
• Take niacin
• Fast before and after
• Consume cruciferous vegetables

So fast and nice to the point, thanx!
I was double CT-d in the hospital when I had a kidney stone. The first time the doctor made a mistake. He ordered a chest CT when I complained about a lower back pain. Two CT in one night! I was vomiting and had diarrhea for many weeks after that plus my face aged 10 years in a month. When I visited my general practice doctor she literally laughed at me when I told her it must had been because of the CT. She said CT does no harm.
She lied to you. My abdomen and pelvic ct scan for a suspected kidney stone literally microwaved my insides enducing radiation poisoning. Brutal. I threw up for months and my skin changed coloration, beard quite growing, could barely eat and went through symtoms of being burned alive with reduced organ function accross my body. 180 t levels from the radiation blasting my balls. Get a ultrasound next time. I learned the hard way. 1 ct scan and hundreds of xrays is similar to the radiation exsposure as some Hiroshima survivors. They are carelessly radiating the hell out of healthy people with these scans
You were suffering from radiation sickness and that scan trashed your gi system from cell necrosis from the radiation otherwise known as radiation entritis. She lied to you as they all do
Have your hormone levels checked, if your on the lower end of the normal t level range say under 400, that scan most likely nuked your balls as well.
I wonder how the new UA-cam rules taking affect on 10 Dec will affect Dr. Berg channels. We can't lose this channel its life changing.
Thank you Dr. Berg I didn't not know the difference between CT and MRI. I have heard of them but never knew much about them. I needed this information!!!
Decision made!! This has been on my mind for a while. Thank you Dr. Berg!!
The most informative videos on UA-cam....period! 💯👏👏👏
Feels like you've been going through my search history. I was just curious about this days ago. Lol thanks doc.
Unfortunately most people get a CT scan because:
- its cheaper which insurance companies like
- its faster which allows a hospital to use it more often during a day
- hospitals want to use it as long as possible because of ''return on investment'' before replacing all CT with MRI.
- the hospital simply doesn't have a MRI
- the hospital has a MRI but the waiting list is too long
You can get about 1 year worth of natural radiation within 15 minutes from a CT scan. Your doctor should have a very good reason to refer you for a CT over a MRI. Question your doctor.
More like 3 to 15 years of radiation in 1 scan alone unless it is a head ct. They are radiating the hell out if people when they could use an mri or uktrasound instead. They also are not transparent about the risks or radiation exspsosure upfront and provide zero disclosure forms or many health conscious people would definately decline a ct
My intake from this video is try to be as healthy as possible to avoid getting acute diseases, so that you never have to be exposed to any of those MRI/CT nightmares.
thank u Dr yr vidoes are really priceless .. I use them as a trusted reference .. waiting yr next video 👍🏻 best regards from the middle east
I had a few CT Scans over the past week which revealed I have/had bowed cancer. Surgery so far seems to have removed the tumours from my large intestines & bladder but it had also spread in small amounts to my liver which they say will be dealt with by chemotherapy. I have stage 4 cancer, I’m 45 and in hospital recovering. I had lost weight and strength so needed a blood transfusion before surgery. On the operating table they apparently had a choice to let me go or cut more so they cut and I’m still here fighting. They have suggested my days may be numbered by the liver cancer but as a husband and father I will fight every day to live a good and full life with my family.
I current have a stoma and have been struggling to eat enough proper foods, I’m enjoying milk, yogurt & ice cream at the moment. I have been vomiting litres of nasty bile and now have a drainage bag down my nose to hopefully try and control it. I may be able to go home in a week or so and chemo will commence a few months after when I’m strong enough.
I did have an ultrasound first and had included some niacin & fasting prior to scans and surgery.
''I’m enjoying milk, yogurt & ice cream at the moment.'' Isn't ice cream food for cancer to grow faster?
I wonder how is this person now ?
@@good2freelance1 they cut his intestines and bladder, so probably not well. Also he had liver cancer. I don't really see a way out
please keep on fighting, I will pray for you 🙏
Why you are called lazyJesus
I dont know you, but I am so sad to hear about your health, my mother died of colon cancer so I feel really sad when someone talks about that topic. May God help you and provide you with health.
First I love your channel Dr! Especially the diet videos I’ve learned an abundant amount from you! This video is very interesting, I am a concrete contractor and I’ve built many foundations for MRI machines and linear accelerators for Memorial Sloan here in NYC. I would love to see an explanation video on how linear accelerators work..
Thank you Dr I really appreciate that.
i was little bit concern & confused about on both of them now I’m more clear about how they work.
DR Éric Berg thank you for the useful information you bring us!!! 👍
Very informative and to the point video👍🏾👍🏾👍🏾, I have wondered about the same things too. Good to know what one can do before a CT scan in preparation👍🏾
I just had an MRI yesterday and I feel a lot better about it now!
My sugar level is 172 fasting and 299 post meal 2 hrs I'm adopting your intermittent fasting and low carb diet today day 1
Gives me some peace. I have to have an MRI done tomorrow for a brain tumor.
Thank you!
Dr Berg that was just so awesome and helpful. I had a CT scan earlier this year though I didn't want to have it. I have been fasting a lot and had no idea that fasting was a way to help my body and counter any possible damage.
@erick granados I had one 3 years ago
@@neohero97 any cancer yet?
EXELLENT subject matter Dr. Berg....good information. 👍
Very informative. Thank you. Working in the hospital I see CT scans ordered as easily as they write a script. Good to know...
Thank you very much Dr Berg 🙏very helpful topic 👍🌷🌿💓
Good comparison. Thank you for the lesson 👍
Thank you my fav. Dr berg♥️..great great great info .!!😊what to take,after a ct scan,wow didn't know,thank you so much.!!
Hey Dr.Berg, i love your videos and am watching you since 2 years and if the content stays that qualitative then i will keep watching for sure.
I have 1 request: When you recommend a nutrient like niacin in this video, could you tell the reason why this specific nutrient(s) is(are) important. And if there are more reasons, please tell at least the most important one(s).
THANKS for helping millions of people by education and even more people by the education your viewers get that they share with their loved ones. i love you
Thank you for always giving accurate health minded information about all things consumed! We sure appreciate the gift that God has given to you!
Thanks for the VDO Dr. Berg. One question: Can a Coronary Artery Calcium score be determined via a MRI or is it only possible to obtain this score via a CT-scan? Thanks!
I have been feeling dizzy, so my doctor ordered an CT, will have it done on Friday, nut now this come up!
I am schedule for one too!! Now I'm worried!! I have been having digestive issues and been feeling light headed and dizzy as well. Turns out I had kidney stones and anemia and the scan is to check some other stuff.
Do it! Benefit outweighs risk
@@ScottLive1 thanks!
How did it go
Thank you for making nice and easy informative video. 👍🙏
Thank you, Dr Berg.
With an MRI, you get music! 😁🎶 I was in the hospital for a week over the summer. I had one CT scan, and about 7 or 8 MRI's. I wasn't worried about it, but I am glad to know I got more of the less harmful one.
👍
MellieBellie722 with music is could create cancer I think because headphones are signals
CT should be used only when there is NO choice. Besides, MRI and CT are both very expensive, but they almost cost the same. The equivalent of 200 xrays is too much. I had no idea it was that much radiation. Besides, with MR1 3T and contrast you can get good images.
Having a CAT scan tomorrow so this is sooo helpful thanks
Have a meowful day!!
Dr Berg, you rock, as usual:-). Many thanks.
Thanks, Dr Berg!
Nice differentiation
Yes - thank you so much.
Good good information, now I understand the when-it should be used and what it can actually find. It seems to me cat scans are used indiscriminately and too often when one MRI would have found the health problem and not subjecting us to so much radiation and in the end run less cost to health system.
.
Wow I did not have any idea! Thanks Doc😊
I love ya needed this video at this very moment😊❤️
Great info on fasting before cat scan!!
Good info, thank you!
What about the contrast dye used for MRI - gadolinium? Much skepticism about the body being able to get rid of it.
I like MRI's the weird sounds they make makes me feel like im in some sort of a classic trance concert : )
Especially that jack hammer sound!
Very useful video.
I just completed a CT colonography, how much niacin and cruciferous should I take and how to take them? Thanks a lot.
I would like to learn about contrast dies please
Thank you
In 2005, I had a personality change. Like a different person. I had a Brain MRI. I had developed a brain, fluid filled, cyst; about the size of a walnut. Any operation (at that time) would be very dangerous. So I learned, over the following two years to accept, and like, who I had become, and accept that death could come for me any time... Now, it's 14 years later, and I'm sure there have been brain surgery advancements; but my "living on the edge," has a unique quality of it's own. The MRI took a couple of minutes, and cost over $6,000. No telling what one costs today.

I have an MRI every other year for MS-my insurance is charged about $5800. I have to pay approx, $1000. I am going to tell my neurologist that I refuse to have dye injected into me anymore and since there has been no change for many years I don't think I need the MRI anymore either. The dye is full of heavy metal and I feel like it is negating all the hard work I do with my diet.
@@sarahicks9351 so is it bad to get an MRI?
MRIs cost a lot more, so if the needed imaging can likely be accomplished with a CT the doc, and the insurance, will choose the CT.
That's because money are worth more than lives
All about the 🤑dollar$$$$$$. So SAD!
@@Kube_Dog Well, since you´re believing to be superior to others, you must be right. Bravo
I have stage 4 cancer and every six month they wanted a Cat Scan, I did this for about two years and said that's enough. I have non Hodgkin's lymphoma, along with ulcerative colitis............Can they use the MRI instead of Cat Scan for my type of cancer?
Well explained.
Thanks for watching!
How about the “mri contrast metals injection “ that some mris required before getting the MRI ???
Hi Dr Berg, excellent as always. Can you explain how to detoxify from CT's ?? Can spitulina helps??
Thanks
You can't the radiation damage to your cells and dna is permanent. If you did not have a bad reaction the good. Just never get another ct scan again no matter what your dr says. Mris and ultrasounds do just fine and won't microwave your insides
You mean the gadolinium? First you need to see if it's still in you by way of a heavy metals test. If it's not you're good to go, nothing to do.
Hi Dr Berg, I had an abdominal ultra sound because I have lower abdominal pain every nos and then. They found lesions on my liver and something in the biliary track. My dr wants me to get a CT scan. Are these good reasons to get one?
I’ve had 4 ct scans this year. Two on my head and two on my abdomen, one was with contrast and messed me up big time.
I had no idea how much radiation I was receiving.
Never again.
How did it mess you up?
Losing my hair, the big thing was the iodine contrast that really messed up
Can you make a video about non anemia iron deficiency and what leads to it and what to do about it and also what blood markers to watch and especially what ferritin should be, there is so much different info out there that this would be extremely helpful! Can mold and EBV, stress deplete iron? THANK YOU!
@@Diogenes-II can you tell a bit more about your claims?
There are plenty of other blood markers for iron deficiency too.
@@Diogenes-II no I don't. Also my ferritin has always been around 9-20. Other iron markers also low and I'm white as a ghost with iron deficiency symptoms.
@@Diogenes-II it kind of makes sense but then again why would all the blood markers be low like red cells are smaller, combined iron low, transferritinreseptor prosentage really low. Body needs iron to work and i feel better when my iron levels go up cause i actually can function 😁 so this is very confusing. I do have activated ebv, or at least had. Also high cortisol. I take magnesium everyday in the best forms and quite high dose.
@@Diogenes-II i take exactly those forms of magnesium, i also rebound and dry brush, sauna etc. Still seems that everything gets stuck really easily.
CT or MRI for checking thyroid nodules for malignancy? I really need to know, please!
thanks
Just had an mri in Sunday and I was so scared, I opted out of an ct
Doc could you make a video on oxalate toxcicity.
Omg no wonder I’m going in Friday for surgery on my throat. Had a million cat scans & x rays in my life from multiple car & motorcycle wrecks and at least 15 mri’s
Wish I know this before getting one
Dr Berg Where can I get niacin? They want to give me another ct scan for lung nodule ….I don’t know what to do. I’ve already had 2 because I had E. coli that turned into Sepsis that’s when they saw a nodule…please help me to know what to do…I’m 55 female do keto…I’m so nervous
Is there different dose levels for different body parts like the for example does it have to be on low power when scanning the head?
Can you plz talk about the side effects of IV antibiotics and vision ? I had 8 IV antibiotics and 3 oral courses to treat an infection after surgery and I got better. However, my eye sight was -2.75 for over 30 years.. now in less than a month, it went down to -3.5.. even with wearing contact lenses I can't really see very well.. I'm worried that it's not reversible .. doctor said my body will need time to heal .. like few months .. but I'm worried .
Which is the better one for checking the arteries?
What is your opinion of dental X-rays
I declined a CT scan when I was in a car accident. I felt fine, I wasn’t about to nuke my brain. 😤
you only looking at the cons of CT scan. need to look at the pros too.
Nuke is more like 200,000 chest x-ray not 200
The dumbest thing you could ever do…
You could have been developing a tumor because of any brain injury/trauma.
You knows, it there can be one in development right now and not know of it until its too late, right until it has grown and started to impact on the brain…. Headaches, balance issues etc.
How can you detox Devinity dye from the body? Is it a heavy metal?
I didn't read all the comments but I'm going to ask this question. What about thermal imaging? Would that be a better alternative then either one?
''thermal'' mean heat. Not sure what you can see with slightly different temperature in your body
Saw your CAC video though
Dr Berg,, I've had several CTs in relation to migraines. The last one probably 8 years ago. Anything I can/should do now about the damage to DNA that might have occured?
Why did you have so many just for migraines? Do you have an underlying condition?
Please compare thermography to these two tests, It's better for cancer -?
I am already underweight (175 cm and 56 kg), and I was recently diagnosed with Functional Neurological Disorder. Can I do keto diet and IF? Thank you!
Urologist recommended a CT scan w/ contrast for kidneys. I already had one but without contrast or dye. Also had an ultrasound.
He said I don't have stones but I have pee in there the tube might be somehow restricted.
Anyway, should I request an MRI instead?
I’ve been getting a lot of x rays for my broken bones. What should I eat to reverse the x ray damage?
Fasting or intermittent fasting is the best.
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?
Heyy Doc!! Would an MRI be better for strained intercostal muscles?
Would you add iodine /sea veg. For the radiation removal ?
Hi Doc! What is your say about the contrast use in MRI . And how to flush it out?
Read the latest article from Dr Mercola about it. It will open your eyes to the danger.
mandograssable thnx . I will
Be very careful about getting a MRI if you have a pacemaker! Always be sure the doctor and imaging place are aware. Of course they should already have it on file but better safe than sorry.💕
Hi Dr. Berg, just had a head CT scan yesterday and I am very worried about the implications. I'm on keto diet now for a month and wonder if that would help? I did not receive any warnings prior the head CT Scan or was let aware of the amount of radiation I was going to receive. Any comments on that?
Hey man I'm fine, got a dose of 11 millisiever and already had 3 other CT prior to that (all unnecessary one and 2 as a teenager that could have been replaced by an MRI). Unfortunately, it looks like CT are cheaper than MRI (therefore being pushed by insurance compny) and that most patients have no clue about what it does to your body. I just found out about CT radiation after the last one I did. To my biggest surprise, even the doctor that prescribed it at the hospital did not know the absorbed amount of radiation and told me that the radiations from the CT I just had were equivalent to one transatlantic flight. I had to email the radiology dept. in order to know the msv amount I got, none of the staff there knew and finally had to talk to the physician.

@@boogyigloo3880Hey I had to have 2 head CT scans for falls in my 20s. I felt they were unnecessary but I'm a hypochondriac and wanted to make sure I was okay. I really regret them now. But there isn't much you can do, what's done is done. Just eat healthy, exercise and live happy. You'll be alright.
Also I asked my radiologist how much I absorbed, he said one thing while my results said another. Made me angry, but thankfully the results were much lower than what he said.
if you use CT many times, you might become a super hero with super powers.
True, but more likely a bald spectator who is often low on energy.
I read a lot of article the danger of MRI. because of the chelated gadolinium. And some people have a reaction after their MRI. Like the Pheripheral Nerve Stimution. because of the magnetic gradient fields. And some people have headache and twitching in the nerve. So this is dangerous I must say.
What is the purpose of fasting before and after ct scan?
I would guess because it causes lower glucose levels to reduce the oxidative stress, and autophagy and HGH to help repair any damage to cells.
Dangerous ionizing radiation is used in CT scans. MRIs do not use radiation, therefore they are much safer.
One typical CT scan is equivalent to having 300 regular x-rays.
Hot doggit, I am an early bird this morning! This information was worthy of my getting out of bed!😂😂😂
We need video about carrot juice How it is used to cure cancer while it contains high amount of sugar and why dr Berg in his new book states that Carrot juice is the least damaging juice.
@@Fjerid Many doctors recommend carrot and beet juice to cure cancer without referring to Gerson therapy..just healthy organic diet without (sugar) but carrot juice is included in the diet!

Should I be worried about a head CT Scan done to me about 7 years ago. Everything came out normal. Had Benign Vertigo Positional.
Tq
what do you think about the nuclear scan? Oder nuclear medicine?
Main difference is that here in Europe they're both free....whereas in the States each costs about 3000 dollars per pop at the hospital.
No the one that are free are 1 to 2 years waiting...so we are pushed to do it on our own cost.
Wouldn’t it be malpractices if one needs soft tissue imaging and the doctors push for ct scans knowing that an mri is more accurate for the circumference? I feel like I’m being made into a future customer for fighting cancer. Please help
They will radiate the hell out of you Iif you let them. Fight for the mri or ultrasound and never get s ct scan unless you are literally dying. I suffered from radiation poisoning after my ct.
Hey doc, just for fun. How many cats needed for cat scan.
I will have to do a MRI for my brain next month!I hope it's nothing serious
