Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI) is a valuable diagnostic imaging tool used to diagnose various diseases of the human body. MRI is most often used to obtain images of the brain, spine, most joints of the body and the vascular system.

MRI uses a large magnet and radio frequency coils to create cross-sectional images or "slices" of the body. The magnet used is approximately 30,000 times stronger than the earth's magnetic field and as such, can actually pull the molecules of the body into alignment with it. Radio frequencies are then beamed across the body to cause these molecules to vibrate, or "resonate", and give off a radio signal of its own. Specialized coils then collect these signals and make an image of the area being scanned.

MRI is a safe non-invasive procedure for most patients. However, if you have metal in your body such as pacemaker, cochlear (ear) implants, vascular aneurysm clips, shrapnel, or metal shavings in your eyes, please check with your physician before having an MRI procedure.

If you are claustrophobic or experience pain while lying on your back, please let your physician know before your MRI scan is performed. Your physician may prescribe a relaxant or pain medication to make you more comfortable during your scan. SRHC now offers MRI services utilizing an "open" MRI unit that may be beneficial if you suffer from claustrophobia. Please bring someone with you to drive you home, as medications of this type may impair your ability to drive.

There is no special preparation for an MRI procedure. When you arrive for your scan, you will be asked to fill out a questionnaire regarding your medical history and what types, if any, metal or implants you may have in your body.
