How does the Virtual Colonoscopy (VC) compare to a Colonoscopy?
The VC is a screening tool that allows visualization of the entire colon from outside the body. The colonoscopy is an invasive diagnostic exam that allows doctors to remove a detected polyp at the time of the procedure. The VC is FDA-approved for visualization of polyps of 1 cm and above. Cancerous polyps are considered to be 1 cm and larger.
