What Happens During a CT Colonography?
CT colonography or “virtual colonoscopy” is an X-ray test designed to look for colon polyps and cancers. First, a radiology technician inserts a tube into your rectum and air is pumped into the colon until it is fully distended. Then, you are asked to hold your breath while lying on your back and a CT scan is performed. You then turn over onto your stomach and you again hold your breath while a second CT scan of the abdomen and pelvis is performed.
