I sent this as a PM to you since I saw you posted in the live chat while I was away but figured I'd post it in your thread as well so others can see it.
Welcome to the forum!
CT scans and X-rays put you at a higher risk of developing cancer. There isn't a study that shows how bad it can be long term though as CT machines are still fairly new relatively and all of us who have had a lot of CT scans really wont know how badly it will affect us just yet.
"CT scans do expose you to more radiation than regular x-rays. Having many x-rays or CT scans over time may increase your risk for cancer. However, the risk from any one scan is small. You and your doctor should weigh this risk against the benefits of getting a correct diagnosis for a medical problem."

CT scans can have the radiation level adjusted so you can request the lowest setting needed.
I don't see why you would need 24 CT scans honestly but in the future you can opt for an MRI or MRE as they don't use any radiation yet also give a very detailed picture to help with both treatment and diagnosis.
To add to that though you can also do a Pill Cam and even a small bowel follow through with x-ray will have WAY less radiation than a CT scan.
CT scans are often used automatically without a second thought so learn how to say no and try to suggest something else. Have your GI run some real tests and if a CT is all they can think of then find another GI. If you're doing the ER/hospital route, you can request an MRI or small bowel follow through (again, much less radiation than a CT).
