Computed tomography (CT) of the body uses special x-ray equipment to help detect a variety of diseases and conditions. CT scanning is fast, painless, noninvasive and accurate. In emergency cases, it can reveal internal injuries and bleeding quickly enough to help save lives.


Tell your doctor if there’s a possibility you are pregnant and discuss any recent illnesses, medical conditions, medications you’re taking, and allergies. You will be instructed not to eat or drink anything for a few hours before hand.


If you have a known allergy to contrast material, your doctor may prescribe medications to reduce the risk of an allergic reaction. These medications must be taken 12 hours prior to your exam. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.


If you are to have a contrast injection, you should not have anything to eat or drink for four hours before your CT scan.

If you are allergic to iodine or have asthma, please inform the technologist 5-7 days prior to your exam.

If you are taking Glucophage, Glucovance, or Metformin, you will be asked to refrain from taking this medication the day of the exam and for 48 hours after the scan is completed.
