CT - ABDOMEN & VIRTUAL COLONOSCOPY How does CT work? CT uses X-rays to perform its work. These X-rays come from an X-ray tube which is placed inside a square machine called the gantry. The part of your body to be scanned goes inside a hole in this gantry. Why is CT such a good modality? Ordinary X-ray pictures are one-dimensional representations of body parts but CT allows us to section the body to view its inner parts. Thus, the skull X-ray only shows us the outer part, whereas CT shows us the inner parts of the brain. Where is CT useful? All parts of the body can be scanned with CT. For each part, there are specific indications or reasons for scanning. Your referring doctor and the consultant radiologist are the best judges of the usefulness of CT scanning in a specific situation and areas. Are there any dangers of CT scanning? Though X-rays involve radiation, there are no dangers, in practice. In women who are pregnant, however, CT scanning should be done after weighing all the risks. What is the injection that I may receive? Majority of the patients will be injected with a "dye" which enhances the ability of CT scans to pick up abnormalities. This is routine. The dye used is a non-ionic contrast medium, which is much safer than the routine, cheaper, ionic dyes. Are there any complications because of the "dye"? 0.5% of patients may get nausea and redness of the skin. Though severe reactions are known, these are very rare and uncommon.


Why is CT - ABDOMEN & VIRTUAL COLONOSCOPY done ?

The major reason for performing CT colonography is to screen for polyps or cancers in the large intestine. Polyps are growths that arise from the inner lining of the intestine. A very small number of polyps may grow and turn into cancers.

Why is CT - ABDOMEN & VIRTUAL COLONOSCOPY ?

CT - Virtual Colonoscopy is used to identify abnormalities in your colon and rectum. These abnormalities include diverticulosis, bleeding or signs of colorectal cancer. The test is also used to locate polyps and growths of tissue in your colon and rectum. These polyps and growths can be precancerous. The procedure uses a CT scan to construct images of your large intestine. After the scan, a computer combines the images of your colon and rectum to produce two- and three-dimensional interior views. In some cases, an MRI is used instead of a CT scan. Virtual colonoscopy and conventional colonoscopy use different tools to retrieve the images of your colon. Conventional colonoscopy uses a colonoscope. This is a long, lighted tube that�s placed inside your colon and rectum. It uses a small camera to send images of the area to a video monitor. Virtual colonoscopy uses a CT scan or MRI to take pictures of the inside of your colon from outside your body.
