Virtual Colonoscopy

CT Colonography , Baltimore, MD - State-of-the-Art Imaging Technology

Overview of a Virtual Colonoscopy:

  • A virtual colonoscopy uses a low-dose CT scan to examine the colon. Compared to a traditional colonoscopy, it is less invasive and does not require anesthesia. 
  • Scans are reviewed by a radiologist, looking for polyps inside the colon. If polyps are found, they will be removed to avoid colorectal cancer. 
  • A virtual colonoscopy is great for patients who do not wish or unable to undergo anesthesia, or who are on blood thinners.
  • A virtual colonoscopy can be completed in just 10 to 15 minutes.

What is a Virtual Colonoscopy?

A virtual colonoscopy is a procedure that looks for small growths inside your colon called polyps. Polyps grow on the inside of the colon may turn into colon cancer. The Screenings are advised beginning at age 50, and earlier for those with a history of colon cancer. If no polyps are detected, a physician will normally advise patients to get screened once every 5 years.

How is a Virtual Colonoscopy Performed? 

The virtual colonoscopy is completed at our medical center and only takes 10-15 minutes. A thin tube will be placed into your rectum to inflate your colon with air. Some patients report a feeling of fullness as this is done. 

You will lie face up on the bed that slides into the CT scanner. The radiologist will leave the room, but you will be able to hear and talk with him as the procedure is going. 

The bed will move you into the scanner. You may hear some whirring and clicking noises – these are normal and to be expected. You may be asked to hold your breath at times. The scan may need to be repeated while you lie face down.

What is the Prep for a Virtual Colonoscopy?

Before having your virtual colonoscopy, you will need to prep your bowel. Bowel prep empties the colon so that the CT images taken will clearly show the colon

  1. 24 hours before your procedure, your diet will be limited to clear liquids. These include but are not limited to water, clear broth, or an electrolyte solution (with light colored or no dye, as dye interferes with the imaging.)
  1. The night before the procedure, you will be given a strong laxative to help you empty your colon or any remaining solids. Plan to spend the night inside, as laxatives often include frequent loose or liquid bowel movements. 
  1. Just before the procedure you may be given a liquid to drink called a contrast media. This helps us to better view the inside of your colon on X-rays. Talk with your healthcare provider and the radiology staff if you have any questions.

Is it Less Painful than a traditional Colonoscopy?

A virtual colonoscopy is more comfortable than a traditional colonoscopy

VC is far less invasive than a traditional colonoscopy. A small, short tube is placed into your anus and air is pumped into your colon. This inflates your colon so that polyps and other growths are more easily seen. Pumping air into the colon carries a small risk that it may cause a tear, but is less likely with this procedure than with a traditional colonoscopy. There is also no scope inserted into the colon, which greatly reduces the likelihood of pain after the procedure. Most people return home without help. You may resume a normal diet and activities.
