The Method, Reasons and Risks of an Abdomen Scan

Risks of a scan. An abdominal CT scan does have some medical risks, but they are minimal. Some people have an allergic reaction to the contrast dye when it is used, usually limited to hives and itchy eyes. On rare occasions, a patient may have a severe reaction that leads to anaphylactic shock. This is a life-threatening condition that will require the intervention of medical professionals. There is some research that suggests people with seafood allergies may be prone to contrast dye allergies as iodine is present in both. Most people simply experience intravenous contrast dye with a strange, warm feeling as the dye enters the bloodstream.
