Once you arrive at the UIC, you will have to register at the front desk. You will be asked to pay for the procedure at this time. You will get changed into a gown. The Technologist will explain the procedure to you and escort you to the CT room.

How long is the procedure?

Be prepared to be here for about one hour.

What can I expect during the procedure?

You will begin the procedure by lying on your back. A thin tube is then placed into your rectum and contrast and air is pumped into your colon to distend your bowel. The table is then moved into the scanner and pictures are taken. You will be asked to hold your breath and to hold still during the procedure. Then you will turn onto your stomach and the procedure will be repeated.

What can I expect after the procedure?


After the exam is complete, the results are sent to your doctor and you may resume normal activity. It is suggested to eat lightly after the exam since the bowel cleansing agent might still be active.


Are there any risks to this procedure?

There is a risk of perforating the bowel and brief rectal discomfort.
