What is CT Virtual Colonoscopy?

CT Virtual Colonoscopy is a minimally invasive method to screen and diagnose colorectal cancer. A CT scan is performed and special virtual reality computer software takes the multiple 2D images and combines them together to create a 3D model that is easier to view from multiple angles. Our Radiologist will look at your digestive tract to find polyps and other abnormalities.

This is all done without sedation, and without the need to fill the colon with barium (barium enema) or insert the long larger tube that is used during a conventional colonoscopy.

We believe that a CT Virtual Colonoscopy is more comfortable, faster, safer, and less expensive than a conventional colonoscopy. A Conventional Colonoscopy is considered the gold standard and is the most accurate test for detection of polyps, but it is associated with an increased risk of complications and expense.

CT Virtual Colonoscopy is a very good screening test for colon cancer, for those patients who want a less invasive study and do not have any symptoms or family history.
