Virtual Colonoscopy


Virtual colonoscopy is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum.

During a 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.

When is Virtual Colonoscopy used?

Virtual colonoscopy is one option used to screen for colon cancer and often can be used when a colonoscopy cannot be safely completed due to a variation in the person’s colon anatomy and concern for a higher risk of a perforation or when the risk of sedation is very high due to underlying medical conditions. One significant drawback of a virtual colonoscopy is that polyps cannot be removed and, if they are noted, a colonoscopy is required for polyp removal.  Discuss your colon cancer screening options with your doctor to determine whether virtual colonoscopy is the right option for you.
