3-D Virtual Colonoscopy
3-D virtual colonoscopy is a noninvasive procedure that provides a detailed image of the colon and rectum's interior lining. The procedure can detect and diagnose medical conditions, including precancerous polyps and cancerous tumors.
The procedure consists of two quick CT scans, one while lying on your back and one while lying on your stomach. Each scan takes less than a minute to complete.
Before the scan, your scan will be inflated with air or carbon dioxide to get a better image. You may experience a feeling or pressure or fullness, but there is typically no pain.
After the procedure, your radiologist will analyze the images and forward them to your physician, who will discuss the results with you.
