Exam process

• Next, a tube will be inserted into the rectum and CO2 gas will be used to fill the intestine. This gas allows images to be taken by the CT scanner with minimal stomach cramps.
• Images are taken while you are lying down on your back and on your stomach. Sometimes images are also taken while you lie on your side.
• Some people experience mild cramping or bloating during the exam.
• The exam lasts about 30 minutes.
• You can resume your normal eating habits right after the exam.
• If you are driving a vehicle, you must wait one hour after the exam before leaving. If someone is driving you, you can leave the hospital immediately after the exam.
