CT or “Virtual” colonoscopy is a state of the art procedure in which a CT scanner, virtual reality computer software, and a specially trained Radiologist look inside the colon (large intestine) for polyps and cancers. Most patients report that the virtual colonoscopy is more comfortable than either the barium enema or conventional colonoscopy.
Colorectal cancer is a leading cause of cancer-related deaths and can potentially be prevented if colon polyps are discovered and removed early. Individuals at greatest risk of developing colorectal cancer are over 50, and have family history of colon cancer or polyps. Virtual colonoscopy is particularly useful for patients who have difficulty with traditional colonoscopy or whom have had a failed traditional colonoscopy.
What you should know
How is a CT Colonoscopy performed?
At the time of your examination a small tube is placed in the rectum to inflate the colon with carbon dioxide, which is later easily absorbed by the body. A low radiation dose CT scan is performed while the patient lies on their back and then again on their stomach. The total time for the procedure is 10-20 minutes. A specially trained Radiologist analyzes both the 2D scans as well as the 3D “virtual reality” data that is created. The 3D images provide the appearance of driving through the inside of the colon with a small camera. Polyps or cancers are noted, measured and described using this roadmap. Patients can resume normal activities immediately after the procedure.
