Announcer: A CT colonography is a test to look at the inside of your bowel. Your bowel needs to be empty for the test, so you have to follow a special diet for a couple of days beforehand, usually a low-fiber or liquid diet. You will be given instructions about what you need to do. Before the test, you take a laxative or a special liquid called "gastrografin". This is a dye to help make the scan clearer, but also works as a laxative. You will have diarrhea, so it's best to stay at home, close to a toilet. On the day of the test, you can continue to drink clear fluids up to a few hours before. The radiographer puts a small tube called a "cannula" into a vein in your arm or the back of your hand. You may have the drug through this cannula to relax your bowel muscles. This reduces cramping during your test. You may need to have an injection of X-ray dye through the cannula. This helps to show the other organs outside of the bowel. You then need to lie on your left side and the radiographer will put a small tube into your back passage to pump air or carbon dioxide inside your bowel. This helps to open up the bowel to make it easier to see it on the computer. You may feel as if you need to go to the toilet or to pass wind. It is normal, but try to keep in as much gas as you can. You then have two or three CT scans in different positions. All of your images will be looked at using a special computer program. This shows up any growths or abnormal areas on your bowel wall. After the test, you may feel bloated, have stomach pains and pass wind. This doesn't last long. To make sure you are OK, you usually stay in the department for 20 minutes. Then, you can go home and eat and drink normally again. You usually get the results within a couple of weeks from the person who sent you for the test.
