CT

Description of Procedure

Computed tomography (CT)—sometimes called CAT scan—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. Depending on the part of the body being examined, a contrast material may be used intravenously or orally to enhance the visibility of certain organs and blood vessels. Depending on the body part, studies can take anywhere from 5 minutes to an hour or more for complicated exams.

Preparation

· Upon arrival, please expect to fill out the required paperwork-patient history form and CT questionnaire.

· Please bring insurance information and any previous studies (films and reports) if related to today’s visit.

· A parent or guardian must accompany a minor for authorization.

· Wear loose fitting clothing without snaps or metals, you may be asked to change into a gown.

· Please do not each or drink for 4 hours before your CT study.

· An intravenous contrast agent or “dye” may be administered through an IV in your arm during the study.

Benefits

· CT scanning offers detailed views of many types of tissue, including the lungs, bones, soft tissues and blood vessels.

· CT is painless, noninvasive, accurate and cost effective.

· CT scanning is simple and fast enough to reveal internal injuries and bleeding quickly enough to save lives.

· CT can eliminate the need for invasive exploratory surgery and surgical biopsy.

Risks

· CT does involve exposure to radiation in the form of x-ray, but the benefit of an accurate diagnosis far outweighs the risk.

· Women should inform their doctor or x-ray technologist if there is any possibility that they are pregnant.

· Nursing mothers should wait 24 hours after contrast material injection before resuming breast-feeding.
