Exam Preparation for Patients

How you can prepare for your imaging exam:

The day of your appointment:

  • Please arrive at least 10-15 minutes prior to your appointment time unless otherwise specified when scheduling your exam.
  • A form of photo ID must be presented at time of visit, please bring insurance card(s) and the order from your referring doctor (if not otherwise sent).
  • Please confirm that if your insurance requires any Pre-Authorization that it has been obtained.
  • Please bring any relevant prior imaging studies and/or reports for comparison. If you had prior imaging done but do not have in your possession, please notify a staff member so we can obtain if for comparison.


  • There is very little preparation required, if any, before an MRI scan except for abdominal exams, you may be asked to be without anything to eat for up to 6 hours prior to your exam.
  • It is preferable to wear loose comfortable clothing, free of zippers and belts, as you will be asked to remove anything that is metallic and change into a gown.
  • You may be unable to have an MRI if you have any metal inside your body, no one with pacemakers, or aneurysm clips can have an MRI. Insulin pumps and other medical devices may have to removed or checked for safety. Please make sure the office is aware prior to scheduling if you have any medical device in your body. If there is a chance of pregnancy or you have ever worked with metal (for example, as a metal grinder or welder), please let our staff know.
  • Individuals who are anxious or nervous about enclosed spaces should tell their doctor. Often, they can be given medication prior to the MRI to help make the procedure more comfortable.

MRI ENTEROGRAPHY – Nothing to eat or drink for 6 hours prior to the exam time.

CT (CAT) Scan Preparation

  • On the day of your exam, wear comfortable, loose-fitting clothing.
  • Avoid clothing with zippers and snaps as metal objects can affect the image.
  • Depending on the part of the body that is being scanned, you may also be asked to remove hairpins, jewelry, eyeglasses, hearing aids and any dentures.

  • If you will be receiving IV contrast, you will be asked not to eat or drink anything for four hours before the exam.
  • If you are breast-feeding and will be receiving intravenous contrast agent, be prepared to pump and discard breast milk for between 12-24 hours following IV contrast administration.
  • If the use of IV contrast is desired, sometimes results of certain blood tests (BUN and Creatinine) will be needed to assess the safety of its administration, as our scheduling specialist may discuss when you book your exam. Please mention if you have a history or kidney disease or undergo dialysis.
  • A history of allergies to IV contrast, sometimes to other medications or foods also affects our decision about the safe use of IV contrast agent. Be prepared to alert our scheduling specialist about these matters at the time of booking, and to discuss them again with the CT technologist at the time of the exam.
  • If you have active asthma and sometimes require medication through an inhaler, please bring your inhaler along.
  • If you use medications to control pain or anxiety, please take them to enhance your comfort during the examination.
