What should I expect during my CT scan?

The technologist will position you on the CT examination table, usually lying flat on your back. We may use straps and pillows to help keep you still and maintain the correct position and to help you remain still during the exam.

If contrast material is used, it will be swallowed, injected through an intravenous line (IV) or, rarely, administered by enema, depending on the type of exam.

Next, the table will move quickly through the scanner to determine the correct starting position for the scans. Then, the table will move slowly through the machine as the actual CT scanning is performed. Depending on the type of CT scan, the machine may make several passes.

How do I prepare for my CT scan?


Your doctor may order blood work before your exam if you are:

  • Over 60 years of age and IV contrast will be used for the exam.
  • Over 60 years of age, diabetic, or have kidney disease.

On the day of your CT scan

  • Wear comfortable, loose-fitting clothing to your CT scan. You may be given a gown to wear during the procedure.
  • Remove bras containing metal underwire. You may be asked to remove any piercings, if possible.
  • Do not eat or drink anything except water for four hours prior to the procedure.
  • Inform your physician of current medications or known allergies. If you have a known allergy to contrast material, your doctor may prescribe medications to reduce the risk of an allergic reaction, or order a different test.
  • Inform your doctor of recent illnesses or other 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.
  • Inform your physician and CT technologist if there is any possibility you are pregnant. If there is a chance of being pregnant, a pregnancy test should be done prior to the exam.

Scheduling and Authorization

If your provider orders a CT scan, we will contact you to schedule your appointment.

CT scans require a pre-authorization form from your insurance company. If you elect to have the CT scan without this pre-authorization, there will be a deposit required at the time of study. You may be responsible for the full balance after your insurance has been billed. If you have questions regarding your insurance coverage or benefits, please contact your insurance company directly.
