MRI
MRI (magnetic resonance imaging) is a diagnostic procedure that combines a powerful magnet, radio waves and computer technology to provide detailed images of tissues, muscles, nerves and bones. Because MRI uses magnetic force and radio waves to create images, there is no radiation exposure during the procedure. MRI is often used instead of CT to study soft tissues or organs because bones do not obscure the organs and soft tissues as they do with CT imaging.
MRI can be used to assess everything from ruptured discs in the spine to detecting brain tumors and vascular diseases. At Mat-Su Regional Medical Center, we offer the following exams:
- Imaging with MRI compatible pacemakers and defibrillators
- Prostate
- Breast and breast biopsy
- Body
- Chest
- Head and brain
- Musculoskeletal (major joints, spine and soft tissues)
- Angiography (MRA)
- Arthrograms
What to Expect
Mat-Su Regional Medical Center has installed a 1.5T magnet. Some of the great features of this equipment are significant noise reduction, quicker scan times and a feature which allows patients to watch movies or listen to their own music. Many patients are able to complete their exams thanks to the movies and music – especially children. Patients are encouraged to bring their favorite movie (no Blu-Ray discs) or an iPod/phone to listen to their own music.
The MRI unit has a large cylinder shape with an opening on each end. You will lie on a cushioned table that moves into and out of the cylinder. You will not feel anything as the exam is performed, but you will hear the unit give off a humming, thumping, clicking and knocking noise as your images are created. Your technologist is also in constant visual contact and verbal communication with you throughout the examination.
Examination times vary based on the exam ordered. You may also require IV contrast with your examination. While this contrast is not the same contrast used for CT scans, blood tests may be required to check your kidney function.
Even if you have a pacemaker or defibrillator, you could still be a candidate for MRI. We are able to image patients with MRI-compatible implanted devices at our facility through additional monitoring. It's important to communicate any conditions to your physician prior to being scheduled for this procedure. Please communicate with your physician prior to your appointment if you suffer from claustrophobia symptoms.
Be sure to report any metallic object in or on your body to the technologist before entering the MRI room.
On the day of your MRI, be conscious about how you dress, making a special effort to minimize accessories containing metal such as belts, jewelry, metallic buttons, etc.
