How bad is a CT scan for you?

At the low doses of radiation a CT scan uses, your risk of developing cancer from it is so small that it can’t be reliably measured. Because of the possibility of an increased risk, however, the American College of Radiology advises that no imaging exam be done unless there is a clear medical benefit.

Can an MRI detect stomach problems?

MRI may be used in diagnosing abnormal growths. It can distinguish tumors from normal tissues and can provide information for the staging (determination of the size, extent, and spread) of abdominal tumors.
