Virtual Colonoscopy, Delaware
What is Virtual Colonoscopy?
Virtual Colonoscopy is a minimally invasive CT exam of your abdomen and pelvis used to determine the presence of polyps and/or other abnormalities inside the colon and rectum.
Unlike traditional colonoscopy, which requires a scope to be inserted into your rectum and advanced through your colon, virtual colonoscopy uses a CT scan to produce hundreds of cross-sectional images of your abdominal organs. The images are combined and digitally manipulated to provide a detailed view of the inside of the colon and rectum.
Who is a Candidate For a Virtual Colonoscopy?
Men and women 50 years of age or older at average risk of colon cancer
Anyone reluctant to having a traditional colonoscopy
Men and women at risk of colonoscopy complications, such as excess bleeding because your blood does not clot normally

How is a Virtual Colonoscopy Procedure Performed?
You'll wear a gown, but likely no other clothes. Sedation usually isn't necessary, but you may be given medication to relax your colon.
You'll begin the exam lying on your side on the exam table, usually with your knees drawn toward your chest. A nurse or technologist will place a small tube (catheter) inside your rectum to fill your colon with air or carbon dioxide as you do a log roll on the table. The air or gas helps create clear images and may cause a feeling of pressure in your abdomen.
For the next part of the exam, you will lie on your back. The exam table will be moved into the CT machine, and your body will be scanned. Then you'll turn over to lie on your abdomen or your side and your body will be scanned again.
You may be asked to rotate into different positions throughout the exam, remain still and hold your breath at times.
A virtual colonoscopy typically takes approximately 15 minutes.
What to Expect After a Virtual Colonoscopy?
You can resume your usual activities after your virtual colonoscopy. You may feel bloated or pass gas for a few hours after the exam as you clear any remaining air or gas from your colon.
