Exam Preparation Instructions

To view the forms listed below, you will need Adobe Reader. You may download Adobe Reader for free at www.adobe.com. Please bring your completed forms with you to our office at the time of your visit.


Great care should be taken when being brought into the MRI exam room due to the powerful magnetic field surrounding the equipment. For your safety, Doctors Imaging has a screening process that begins when you first contact our scheduling specialist and continues until the technologist determines you are ready and safe to enter the exam room.

Medical History – Be prepared to disclose detailed information in regards to your medical history including but not limited to surgical history, possible foreign metal in the body, or medical implanted devices. Sometimes these questions are intentionally redundant.

Implanted Medical Devices – For some patients with implanted medical devices, wallet cards or other documents verifying their MRI compatibility will need to be obtained.

Claustrophobia – If you are claustrophobic or think you may feel overly anxious and confined in the MRI unit, you may request to be scheduled to receive a mild sedative. If a sedative is issued be sure to have transportation arrangements because we cannot administer sedation to a patient who is driving.

Arrival Time – You will be asked to arrive 30 minutes prior to your scheduled exam time in order to fill out paperwork and speak with the technologist prior to the time of your exam.

Clothing – Dress in clothing that is easy to remove, without metal, and leave your jewelry at home. Many exams require a modest gown to be worn.

MRI Brain Prep – If you are scheduled for an MRI Brain exam, eye makeup may NOT be worn.

MRCP Prep – If you are scheduled for an MRCP exam fasting 8 hours prior to the exam is required.
