MRI SAFETY

You will be positioned within a very large, strong magnet.  Therefore, for your safety and the safety of the MRI staff, you must remove all loose metal and change into a provided hospital gown and pants to wear during the exam.
  • If you have any implanted metal or electronic devices please bring your information card with you to your appointment.
  • Metal and electronic items such as zippers, jewelry, watches, hearing aids, pens and belt buckles are prohibited in any MRI room.  If possible, leave these items at home, or you will be given a place to store them during the exam.
  • Those with known allergies to gadolinium (MRI) contrast need to inform their physician’s office before an MRI exam is ordered.  Always inform the physician and technologist of any allergies.
  • MRI is a test of choice for women who are pregnant. Women should always inform their physician and the MRI technologist if there is any possibility that they are pregnant.
  • Breast Feeding:  There is no evidence to show that the tiny amount of gadolinium contrast found in breast milk would cause toxic effects if ingested by a breast-feeding infant.
  • If you have any concerns or questions as it relates to MRI safety, please ask the MRI technologist before you enter the room.

Before Your MRI Exam

  • Patients with pace makers need to notify the MRI department at 314-362-1695 as soon as possible so additional arrangements can be made.
  • Please confirm with your referring physician’s office that any precertification required by your insurance has been completed before your MRI appointment.
  • Take your medication as you normally do, unless your physician has told you otherwise.
  • You do not need to fast for your MRI exam unless otherwise directed by your physician.
  • If you have claustrophobia (fear of enclosed spaces) or anxiety, ask your physician for a prescription to relax you before your MRI exam.  The MRI Department cannot administer medications.  Do not take these prescribed medications until all paperwork has been completed and you are instructed to do so by the MRI staff.
  • Please bring a photo ID (driver’s license or state ID), insurance card(s), a completed Medication Record, and a completed MRI Safety Screening Questionnaire with you to your appointment.
  • If you have a port or a central line please bring your information card with you to your appointment.If your MRI has been scheduled with anesthesia, please arrive 1 hour prior to your MRI appointment time.  You also must have someone to drive you home after the exam.

During Your MRI Exam

  • Based on age and renal status, patients having an MRI done with contrast require a recent serum creatinine lab test.  For your convenience, this test can be done in the MRI department before your MRI exam.
  • For safety, you will be given a hospital gown and pants to wear during the exam.
  • Most MRI exams require contrast.  For the majority of MRI exams, contrast is administered by IV.  A nurse or technologist will insert an intravenous line into a vein in your hand or arm.
  • The MRI machine looks like a large tube that is open on both ends with an exam table running through the opening.  For your MRI exam, an MRI technologist will help you onto the scanner table and make sure you are comfortable.  You will need to lay flat for the entire exam.  To produce the clearest images, you should remain as still as possible for the duration of the exam.  A device called a coil will be placed over the area to be scanned.  You will be moved into the scanner until the area of interest is in the center of the scanner.  If you are having an MRI of your chest or abdomen, you will need to follow the breathing instructions given by the technologist.
  • As the procedure begins, you will hear a loud thumping or humming sound from the MRI machine.  You will be provided with hearing protection.  Once the exam is ready to begin, the technologist will leave the room, but will continue to visually monitor you and communicate with you throughout the exam.  In case of an emergency, you will be given a squeeze ball to notify the technologist that you need assistance.
  • As the procedure begins, you will hear a loud thumping or humming sound from the MRI machine. You will be provided with hearing protection.

  • Most MRI exams are completed in 45 minutes, but depending on the exam may take up to 2 hours. For a more exact length of time for your specific exam, please call the MRI department at 314-362-1695.
