A CT scan is done to study the organs and tissue in the abdomen and to look for signs of:

CT Scan of the abdomen – Possible Complications

Sometimes a chemical (called contrast) is used to help improve the pictures. Complications with contrast are rare. If you are planning to have a CT scan with contrast, your doctor will review a list of possible complications, which may include:

  • Remove any metal objects (eg, jewelry, hearing aids, dentures).

CT Scan of the abdomen – Description of the Test

In some cases, contrast is needed. It helps make certain organs and tissue more visible on the images. It is sometimes given by mouth in a drink. Other times, it will be injected into a vein.

You will be positioned on a special moving table. The table will advance slowly through the CT scanner. You will need to be still during the entire test. As the scanner takes pictures, you will hear humming and clicking. To get a clear picture, the technician will ask you to hold your breath at certain points. You will be able to talk to the technician via an intercom.

After Test

If you had contrast, you may be told to drink extra fluid. This will flush the contrast from your body.
