Virtual Colonoscopy (VC)


Virtual colonoscopy uses x-rays and computers to produce images of the colon (large intestine). The study is performed in a CT scanner after a special bowel preparation. The procedure is used to diagnose colon and bowel disease, including polyps, diverticulosis, and cancer.

Exam Prep & Overview

While preparations for a virtual colonoscopy vary, you will normally be asked to take laxatives or other oral agents at home the day before the procedure to clear stool from your colon. You may also be asked to use a suppository to cleanse your rectum of any remaining fecal matter.

At the time of your exam, you will be asked to change into a gown. A technologist will lead you to the fluoroscopy exam room where you will lie on your back on the examination table. The Radiologist will insert a thin tube into your rectum. Air is pumped through this tube, inflating the colon, to give the Radiologist a better view. The table will then move through the scanner to produce a series of images along the length of the colon.

These images are combined to create a three-dimensional picture for viewing on a video screen. During the scan, you will be asked to hold your breath to avoid distorting the images. You will then be asked to complete this same process while lying on your stomach. The entire exam should take about one hour to complete.
