Why is Virtual Colonoscopy (VC) such a breakthrough screening test?
VC is a non-invasive test. It does not require the insertion of an endoscope throughout the colon. It is quick–completed in about 10-15 minutes. Further, it does not require sedation or anesthesia. Therefore the patient is able to immediately resume all activities, including driving and work. Recent studies of VC show that it is as sensitive for detecting polyps and cancers as traditional colonoscopy. In fact, in many ways, the images provided by VC are even better than those seen by traditional colonoscopy. This is because VC can often see corners, folds, and nooks and crannies of the bowel easier and better than traditional colonoscopy. Furthermore, unlike traditional colonoscopy, which only sees the inside of the colon, a VC also provides images of the rest of the abdomen. While VC images are not a substitute for a complete abdominal CT scan (if one is indicated for other reasons), these VC images can often detect early cancers and other abnormalities in abdominal organs.
