The CT scan, or computed tomography, is an advanced diagnostic test that uses X-rays, a special scanner and a computer to produce detailed images of an area of your body. These images can give your physician a 3-D view of your body, and as a result, your medical problems may be diagnosed more accurately.
How CT Scanners Work
The scanner is made up of a ring containing an X-ray tube and a receptor mounted opposite of each
other. This ring encircles you and rotates around you. With each rotation the tube sends X-rays absorbed during each rotation of the ring. The computer then transforms these measurements into a visual image. This image, or slice of information, is viewed on a video screen during the exam and later converted into photography for your doctor or the radiologist to study.
Understanding Contrast Media
Some CT scans require use of contrast media, which are substances given intravenously or orally to highlight areas of your body. The contrast may cause you to feel warm, and you may experience a metallic taste in your mouth. Tell your technologist immediately if you begin to itch, feel short of breath or experience discomfort.
Preparing for Your CT Test
Your physician will provide you with specific instructions depending on the part of your body being scanned. Some examinations require a special diet or medication before the exam.
Tell your doctor and the technologist if you are pregnant, think you might be or if you are breast feeding.
Tell your doctor and the technologist if you are allergic to, or have ever had any reaction to, iodine, contrast media or shellfish. Wear comfortable, loose-fitting clothing, but you may be asked to change into a gown. Remove hairpins, barrettes, earrings or other objects that will interfere with the CT scan.
The Actual Test
Your technologist will help you onto the CT table, and when you are ready, the table will slide into the ring of the scanner. Your technologist will conduct the test from an adjacent room. You will be able to speak to your technologist through the patient intercom system during the entire exam.
