Three-dimensional computed tomographic (CT) colography, or "virtual colonoscopy," is a promising new imaging method. The technique combines the use of rapid helical CT with computer software capable of rendering images of the whole colon. Using a conventional workstation and a dynamic display of images, a radiologist conducts virtual examinations of the bowel, simulating the way endoscopists view the colon. This method is being promoted by some as a noninvasive screening test for colorectal neoplasia.

Virtual colonoscopy has a number of advantages over conventional colonoscopy. With virtual colonoscopy, the examination is performed without sedation in less time than conventional colonoscopy and . . . [Full Text of this Article]
