Computed Tomography (CT) is a diagnostic imaging procedure that uses a combination of x-ray beam (radiation) and computer technology to depict anatomy at different levels within the body. Each rotation of the beam produces a single slice of anatomy, like the slices in a loaf of bread. Computed tomography allows physicians to see a single slice of the body, just as if you were taking a slice of bread out of a loaf.

A CT technologist explains the procedure to you and asks you several questions about your medical history. You may be given an oral contrast agent to drink before the examination begins. IV contrast may also be injected into a vein in your arm. Both contrast agents helps to visualize tissues in the area being studied. You are alone in the room, however the technologist sees, hears and speaks with you at all times using a two-way intercom.

Your physician provides you with detailed instructions describing how to prepare for your procedure. If you take any medications, ask your doctor if you should take them before your CT Scan. Wear loose, comfortable clothing, avoiding garments that have zippers, belts or buttons made of metal. Note: Women should always inform their physician or technologist if there is a possibility they are pregnant or breast-feeding.

A radiologist, a physician specially trained to diagnose conditions and diseases, interprets the results of the exam. The radiologist sends an interpretation of your results to your primary care physician. Your doctor discusses these results with you and explains what they mean in relation to your health.
