A virtual colonoscopy, sometimes called a CT colonoscopy, is a CT scan of the abdomen after the colon has been filled with air. Rather than using a scope with a camera on the end to perform a colonoscopy, the virtual colonoscopy is performed using CT scanning technology to view the colon from a computer workstation, providing a 3-D image of the rectum and colon without the invasiveness of a traditional colonoscopy. At GI Alliance of Illinois, our providers are proud to offer this alternative to their patients. For more information on virtual colonoscopies in Chicago, IL, Peoria, IL, or Bloomington, IL, contact your nearest location to request a consultation.

Prior to your virtual colonoscopy, we will instruct you to use a prep kit that involves a liquid diet and specialized solution to help clear your bowel. In order for the virtual colonoscopy to work properly, the bowel needs to be free of stool because it could be misinterpreted as a polyp or cancerous growth. Your team at GI Alliance of Illinois can answer any other questions you have regarding preparing for your CT colonoscopy.

Your virtual colonoscopy will be completed in about 10 – 15 minutes using standard CT equipment. In order to perform this procedure, we will place a thin tube in your rectum and inflate your colon with air. You will slide into the CT scanner face up and we will leave the room to operate the scanner from another room. We will be able to communicate through an intercom. As the CT table moves throughout the scanner, you may hear some clicking or other noises — this is perfectly normal. It's important to follow any instructions we give you, such as holding your breath at certain points. If necessary, we may perform the same procedure while you lay face down. There is no sedation required with virtual colonoscopies and you can return to your daily routine right after you're finished.

Virtual colonoscopies are generally a pretty safe procedure. There is a small amount of risk associated with the radiation used during the scan, but we work diligently to ensure our procedures are as safe as possible. Many of our patients receiving a CT colonoscopy in Illinois describe the test as mildly uncomfortable due to the full feeling they feel after the air is pumped into the colon.
