How to Prepare for an Abdominal or Pelvic CT Scan
You should wear comfortable, loose-fitting clothing to your exam. You may be given a gown to wear during the procedure.
Metal objects such as jewelry, eyeglasses, dentures and hairpins may affect the CT images. Please leave these items at home or remove them prior to your exam. You also may be asked to remove hearing aids and dentures or other removable dental work.
You may be asked not to eat or drink anything for several hours beforehand, especially if a contrast material will be used in your exam. You should inform your doctor of any medications you are taking and if you have any allergies. If you have a known allergy to contrast material, or "dye," your doctor may prescribe medications to reduce the risk of an allergic reaction.
Also inform your doctor of any recent illnesses or other medical conditions, including a history of heart disease, asthma, diabetes, kidney disease or thyroid problems. Any of these conditions may increase the risk of an adverse effect.
Women should always inform their doctor and the CT technologist if there is any possibility that they are pregnant.
