Virtual colonoscopy is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum.
During virtual colonoscopy, an imaging technique known as computerized tomography (CT) is used to produce hundreds of cross-sectional images of the abdominal organs. The images are combined and digitally manipulated to provide a detailed view of the inside of the colon and rectum. Unlike traditional colonoscopy, virtual colonoscopy doesn't require sedation or the insertion of a scope into the colon.
Virtual colonoscopy is one option used to screen for colon cancer. Discuss your colon cancer screening options with your doctor to determine whether virtual colonoscopy is the right option for you.
