The use of a radioactive sugar in the bloodstream, combined with a CT scan, exposes the patient to much larger amounts of radiation than normal x-rays.
If you are pregnant (or think you might be), inform your physician and the imaging staff before the procedure.
You will be slightly radioactive for several hours, so you should stay 5-6 feet (2 meters) away from an infant (or anyone who is pregnant) after you leave.
