CT (CAT) Scan

AUR interprets thousands of Computed tomography (CT)—sometimes called CAT scan—exams every year. CT Technology uses special x-ray equipment to obtain image data from different angles around the body, then uses computer processing of the information to show a cross-section of body tissues and organs. CT imaging is particularly useful because it can show several types of tissue with great clarity. CT is a very powerful tool used by many physicians to take images of the head, chest, abdomen, pelvis, and coronary arteries among other body parts.

AUR physicians can interpret CT scans to help diagnose many illnesses and diseases with very high accuracy, enabling faster treatment and often eliminating the need for additional and typically more invasive and costly procedures

Patient Preparation for a CT Scan

You should wear comfortable, loose-fitting clothing for your CT exam. Metal objects can affect the image, so avoid clothing with zippers and snaps. You may be asked to remove hairpins, jewelry, eyeglasses, hearing aids and any removable dental work that could obscure the images. You also may be asked to refrain from eating or drinking anything for an hour or longer before the exam. Women should always inform their doctor or technologist if there is any possibility that they are pregnant. Your scan may include contrast media which will require you to let the technologist know if you are currently breast feeding.
