CT (Computed Tomography)

Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and removable dental work. You may be asked not to eat or drink anything for several hours before your scan, especially if a contrast material will be used in your exam. You should inform your physician of any medications you are taking and if you have any allergies, especially to contrast materials. Also inform your doctor of any recent illnesses or medical conditions, and if you have a history of heart disease, asthma, diabetes, kidney disease or thyroid problems. Any of these conditions may increase the risk of an unusual adverse effect. Women should always inform their physician or technologist if there is any possibility that they are pregnant.

Most CT exams are painless, fast and easy. Though the scanning itself causes no pain, there may be some discomfort from having to remain still for several minutes. If you have a hard time staying still, are claustrophobic or have chronic pain, you may find a CT exam to be stressful. The technologist or nurse may offer you a mild sedative to help.

If an intravenous contrast material is used, you will feel a slight prick when the needle is inserted into the vein. A warm, flushed sensation may be felt during the injection of the contrast materials and a metallic taste in your mouth that lasts for a few minutes.

When entering the CT scanner, special lights may be used to properly position you. You may hear slight buzzing, clicking and whirring sounds as the CT scanner moves during the imaging process. During the CT scan, you will be alone in the exam room, however, the technologist will be able to see, hear and speak with you at all times.

After a CT exam, you may return to normal activities. If a contrast material was given, special instructions may follow.

One of our radiologists, a physician specifically trained to supervise and interpret radiology examinations, will analyze the images and send a signed report to your primary care or referring physician, who will share the results with you.
