This article presents information on a clinical study according to which computed tornographic colonography has high specificity but low-to-moderate sensitivity for detecting colorectal polyps. The study explored in persons at risk, how accurate is computed tomographic colonography (CTC) for detecting colorectal adenomatous polyps? Prospective studies that compared results of CTC with findings on colonoscopy or during surgery in adult patients who were scheduled to receive CTC after a full bowel preparation and either complete colonoscopy or surgery. Reference standards included standard colonoscopy, segmental unblinded colonoscopy, optimized colonoscopy, and surgical findings or results of double-contrast barium enema.
