Before your DIEP breast reconstruction, a CT-angiogram of your abdomen and pelvis will be scheduled. This test produces images of the blood vessels in the abdomen and will help your plastic surgeon map out the defining blood vessels (perforators) and the rest of the abdominal vasculature prior to your surgery.
Before this scan, a contrast material is injected into a peripheral vein. You will then lie on an exam table that slides into the CT machine, a large machine with a hole in the center, and the X-ray tube will rotate around you. Total scan time is generally 20 minutes. You do not have to fast or do anything special to prepare for the CT-angiogram.
