A procedure that links COMPUTED TOMOGRAPHY of the COLON (see also INTESTINE) with techniques that produce three-dimensional views of the mucosa of the large bowel similar to those obtained during traditional colonoscopy. Early experience suggests that the new technique produces better results than barium enemas (see ENEMA) and is almost as effective as conventional colonoscopy. Virtual colonoscopy offers faster results, and image analysis will probably soon be automated. The procedure is easy, non-invasive, safe and complete; once the need for bowel cleansing is eliminated (as seems likely) it will provide a prominent tool in screening for cancer of the colon and RECTUM.
