Learn your positioning properly as it helps so much with getting the patient as close to the isocentre as possible. It optimises your image quality and decreases patient dose. Learn what the phases are in CT are eg arterial, portal venous, delayed etc and what they are most useful for. Learn how to reconstruct your images after the scan and how you can widen your FoV in post processing so you don’t need to repeat scans because anatomy appears ‘cut off’. Once you’ve got the basics, learn how to asses your imaging for basic pathology & quality. Once you have the basic scans down, then you can move onto gated imaging, TAVIs, CTCAs, functional CT etc. Most of all enjoy it and try to understand the principle and aim behind every scan you do. I’ve been a radiographer over a decade having done general, theatre, interventional, cardiac and CT. I’m now going back to university to advance my practice in CT head reporting 😊
The dose will change once there's an actual person on there. There's an automatic exposure and once the scanner calculates the numbers from the scout then it'll be adjusted.
Hi! Great question! I hope you found clarity to your question by now but if not.. here's a short version of it. Once I get to a scanner I can explain on a video more. I do only recall helical, GG helical and volume. Helical is a spiral scan. I believe GG-helical is an add-on to the helical. Volume is one volume and it'll be one quick scan and it can only cover so much. Hope that makes sense I hope to get a video to you soon.
@@RADKhammanyWhen I chose the examination and completed it, the examination does not appear clear and well, for example, the brain examination, the soft tissue do not appear good and clearly
Hahah Hello, hello!! Yes! Its ME! I think if volume was used then one heart beat/breath can cause a lot of motion to see an embolism. If the patient is a mover and having difficulty then MAYBE a volume would be best for the situation.
Good day Doctor, I am quite concerned about the DICOM information of the Brain CT without CE I underwent at age 32. Siemens sensation 16 slice : Total mAs 4751, Total DLP 927 CTDiVol 51.52 Kvp 120 Ref mAs 230 Xray tube current 460 (same value in each image) slice thickness 4.5 exposure time 500 Even tough DLP and CTDIvol is similar with your calculation my Total mAs value isn't it so high? What can be the reason and Did I get overdose radiation? Hope you help, Thanks
do you know how to activate worklist for Asteion system also if i want to take a backup of the operating system how to do that ? hope to cooperate if you have whatsApp num please provide
I do not know the Asteion system. I think it'll be great to be able to communicate publicly for a shared community post. Someone might have the same questions or is able to elaborate more or correct something.
You can also adjust Eff mAs by adjusting the pitch/speed at which that table moves through the gantry.
Thanks for the additional information!
Thank you. Do more videos on the parameters.
Hello! I will try. May you please be more specific so I can narrow down where to begin.
Thank you very much
You're most welcome! Happy to help!
What happens,when we don't maintain effective mAs 251?
Thank you
You are most welcome!
Thank you for the upload. ill be going into CT once i graduate rad school in august. What tips can you give me?
Be polite to your seniors 😉

Great advice and I completely agree. Thank you for sharing! Best of luck on your journey!
You don’t think that the dose for the first two scan are too hige we need it just to put the box in the intreast area
The dose will change once there's an actual person on there. There's an automatic exposure and once the scanner calculates the numbers from the scout then it'll be adjusted.
Can u explain gg helical and vv helical and all complicated stuff on scann type please im pay money for this no one teaching me

@@RADKhammany i hope so im supporting ur channel
I posted a video a few hours ago. Did it explain what you needed?
Hello Ms.👋 I'm working on a CT Scan ,Toshiba and I want to get in touch with you. I have some problems with the protocol and the work station 🥵
Hello, what's the issue?
@@RADKhammanyWhen I chose the examination and completed it, the examination does not appear clear and well, for example, the brain examination, the soft tissue do not appear good and clearly
Did you scan it as a volume scan? Where it was just a very fast scan and it only took one shot?
So the soft tissue is not clear but the bone is?
@@RADKhammany yes a volume scan
Hey I was just looking at toshiba videos. I had no idea this was you until I looked at the name. Lol.
Why don’t you just do a volume?
Hahah Hello, hello!! Yes! Its ME!
I think if volume was used then one heart beat/breath can cause a lot of motion to see an embolism. If the patient is a mover and having difficulty then MAYBE a volume would be best for the situation.
