• Metal: You will be asked before your MR exam if you have any metal in your body. Having metal in your body does not automatically disqualify you from having an MR exam. All patients are evaluated individually.
• Registration: Before arriving, you can print and fill out the MRI and MRI and Pregnancy forms, if applicable, on our Pre-Registration Questionnaire page. This should speed your registration process. 
• Written order: If your doctor gave you an written order, please bring it with you.
• Medications: If you plan to take relaxation medication before your exam, it is our policy that you come with someone who can drive you home.
• Anesthesia: If you are having anesthesia, please also read our MRI and Anesthesia page.

  • Please make sure to inform your technologist if you have a pacemaker or an implantable device.
