Virtual colonoscopy (VC) is a Medical imaging procedure which uses x-rays and computers to produce two- and three-dimensional images of the colon (large intestine) from the lowest part, the rectum, all the way to the lower end of the small intestine and display them on a screen. The procedure is used to diagnose colon and bowel disease, including polyps, diverticulosis and cancer. ...

A method under study to examine the colon by taking a series of x-rays (called a CT scan) and then using a high-powered computer to reconstruct 2-D and 3-D pictures of the interior surfaces of the colon from these x-rays. The pictures can be saved, manipulated to better viewing angles, and reviewed after the procedure, even years later. Also called computed tomography colography.

Advances in computer processing speed and imaging software have allowed for the development of "virtual colonoscopy" (CT colonography). This test still requires an intestinal cleansing but is performed rapidly, without sedation, and without the invasiveness of flexible video colonoscopy. Other intra-abdominal abnormalities may be diagnosed with this screening device. CT colonography is an exciting technique for screening for colon cancer. ...
