A digital colonoscopy, additionally called CT colonography, is a non-invasive imaging technique that uses computed tomography (CT) scans to create targeted pictures of the colon and rectum. it is used to screen for colorectal cancer and detect polyps or other abnormalities.

In the course of a virtual colonoscopy, a CT scanner takes multiple X-ray pics of the colon. Those images are blended to create three-dimensional perspectives of the colon, which may be examined for abnormalities without the need for an invasive procedure.

Digital colonoscopy is normally much less invasive and than conventional colonoscopy. It does not require sedation, and the procedure involves putting a small tube into the rectum to inflate the colon with air for better imaging.

– You will be asked to comply with a special diet and drink a contrast agent sometime before the procedure.
– Clear drinks and laxatives might be recommended to cleanse the colon.

You will be given specific instructions on how to prepare for your digital colonoscopy. There are restrictions on what you can eat and drink before the procedure. These will be clearly communicated to you before hand.

– You will lie on a table that moves through the CT scanner.
– Air could be lightly introduced into your colon to see it clearly.
– More than one CT picture will be taken, and a computer will reconstruct the images into a three dimensional view of the colon.

The technique typically takes about 20 to 30 minutes.
