Computed Tomography of the Head and/or Face

Your physician has referred you to the Diagnostic Services Department at United Hospital Center for a Computed Axial Tomography (CT or CAT scan). CT is an x-ray technique that uses a special scanner and computer to create cross-sectional images of your head or neck. Unlike standard x-rays which produce images of the bony structures of the skull and face, the CT scanner takes detailed images of a particular section of your head, brain tissue, and/or facial bones.

The technologist will position you on the CT table and position your head in a special holder. Velcro bands may be used to keep your head still and additional bands may be used to help support your arms and as a reminder to hold still. The table will move for each scan. As you pass through the opening of the large doughnut-shaped ring, simply relax and remain still. The technologist will monitor your exam from the adjoining room. During the exam, you may hear the sounds of gears and motors coming from the ring.

Very often, intravenous contrast material will be used to highlight certain body parts. The technologist will insert a small needle into a vein in the hand or arm. This contrast medium may cause a warm sensation throughout your body or produce a funny taste in your mouth. These are both normal. If you have had a reaction to contrast media before, or if you begin to itch, are short of breath, or experience any discomfort, tell the technologist IMMEDIATELY.

To get ready for your exam, please wear loose fitting clothing. You will be asked to remove hairpins, earrings, glasses, facial pierces, dentures, or other metal objects. It is not required that the patient follow any dietary restrictions before this procedure.

LENGTH: Approximately 30 minutes

If you are pregnant, or think you might be, tell your doctor and the technologist BEFORE the exam.
