Magnetic Resonance Imaging (MRI)

What is an MRI?

Magnetic Resonance Imaging or MRI is a highly sophisticated medical imaging technique that uses a magnetic field and radio waves to produce very clear pictures of the inside of the body. These black and white images enable physicians to often make a diagnosis, eliminating the need for biopsy or surgery. Since no x-rays are used, there is no exposure to radiation with MRI. The MRI is used to diagnose diseases of the: 

  • Brain
  • Breast
  • Spine
  • Skeleton
  • Chest
  • Abdomen
  • Pelvis
  • Blood vessels

When is an MRI used?

MRI is a good way to identify sports injuries and other problems with joints such as the knee and shoulder. It also is used in the diagnosis of cancer and the detection of injuries to the spine and disks. MRI allows for very detailed images of the heart, enabling physicians to examine how well it is pumping and whether there are any clots or blockages in the arteries - to diagnose or determine the extent of cardiac disease or coronary artery disease.

How do I prepare?

An MRI poses no risk for most people. However, any metallic substance in or on the body may affect the quality of the image and cause discomfort or injury during the procedure, so you must remove all metal on your body, such as jewelry. Before undergoing an MRI exam, be sure to inform your physician or the technologist if you are pregnant or if you have:

  • A cardiac pacemaker
  • An artificial heart valve
  • A metal plate, pin or metallic implant
  • An intrauterine device such as copper - 7 IUD
  • Aneurysm clips
  • Previous gunshot wound
  • Ever worked as a metal worker
  • Permanent (tattoo) eyeliner

Wear comfortable clothing with no metal. Bring your Physician's orders, insurance card, and picture I.D. with you. For your convenience, parking is available in the garage connected directly to our Center for Advanced Imaging across the street from the main hospital. Upon entering the Center, report to the Registration area located on the first floor. After registering for your test, you will be escorted to the radiology reception area where a technologist will provide you further instructions about your procedure.

What can I expect?

A technologist will have you lie down on a cushioned table attached to the MRI. A device called a coil will be placed either above or below the area of the body being examined. This device helps produce a clearer image of the area. The MRI is an enclosed but well-lit chamber. Once you are comfortable, the table will begin to move slowly into the chamber of the magnet. A technologist will stay in contact with you throughout the procedure, both visually and via intercom. During the exam, you will hear muffled thumping sounds for several minutes at a time. A number of images will be made, each taking about 10 to 15 minutes to complete. It is important to try to relax and remain as still as possible, as any movement during the exam will blur the image and produce less accurate results. The length of time of an MRI can differ greatly depending on the exam but most can be completed in 45 to 60 minutes.

When can I expect results?

A highly qualified radiologist will carefully review and interpret images taken during your MRI. A report will then be sent to your referring physician within 48 hours but usually the same day. Please contact your physician for results. If your physician ordered a stat exam, you may be asked to remain in the department until your physician has been informed of your results.
