A Virtual Colonoscopy uses a CT scan to image the colon, rectum and small intestine. The Virtual Colonoscopy is used to diagnose colon and bowel issues, including polyps, diverticulosis and cancer. It also allows the specialist to have a detailed look at other organs such as the liver, kidneys, pancreas, gallbladder and spleen, should they need to. In the past, patients would have a Colonoscopy, a surgical procedure, to examine the colon (also known as the large bowel). However, X-Ray technology has advanced so much that it is now possible to have a virtual colonoscopy during a CT scan. Instead of the need to use an invasive private colonoscopy, our consultants can now examine the inside of your colon from the outside of your body using detailed X-Rays.
