MRI, or Magnetic Resonance Imaging, uses various magnetic fields to produce images of the body from information based on the way the body responds to the magnetic fields, how it relaxes when the magnetic fields are changed, and where the interactions occur in the body.

Rapid City Regional Hospital has a state-of-the-art high-field Siemens 1.5 Tesla Symphony MRI system. This cutting edge technology uses the highest magnetic field and stronger waves to image patients, resulting in maximum patient comfort and shorter exam times.

In recent years, the use of MRI as a diagnostic tool has increased. Physicians can detect diseases much earlier. This dramatically improves treatment possibilities. Areas of the body that may undergo an MRI scan include the head, chest, abdomen, vital organs, joints, spine and extremities such as hands, wrists, ankles, and feet.

The MRI examination poses no risk to the average person, if appropriate safety guidelines are followed. However, because MRI involves a huge, powerful magnet, some conditions make an MRI exam inadvisable. Patients with any kind of metallic implant — for example, heart pacemakers, aneurysm clips, or spine stabilization rods — should make sure their physician is aware before proceeding. Patients do not feel any pain during a scan.

Every patient's procedure is different and tailored to his or her needs. In general however, allow about 90 minutes for your MRI exam. In most cases, the scans are completed in 45 to 60 minutes.

For most exams, you will change into a hospital gown. You will be asked to remove anything metallic, such as glasses, jewelry, dentures, or hearing aids. Patients who are undergoing a brain scan also should not wear make-up because some brands contain metal.

You may receive a painless contrast agent through an IV. Contrast agents, sometimes called dyes, highlight organs and blood vessels so images are clearer and easier to read.

During the procedure, the part of your body to be scanned will be positioned in the middle of the large cylindrical magnet. The opening, or gantry, is much wider than in the past, making the procedure less confining. It is important that you remain still throughout the procedure. Because the scanner makes a knocking noise, you will be offered earplugs or headphones to wear during the procedure.

Rapid results are essential not only for your peace-of-mind, but also for your physician to begin planning any necessary treatment. Experienced radiologists will read the scans and forward the results to your physician usually by the next business day.
