MRI and MRA
|Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to create cross-sectional images of your head, body, muscles and blood flow. Because an MRI provides a clear view of internal organs and tissues, it helps physicians diagnose injuries and other health conditions much faster than with other technologies. For patients who have pacemakers or implantable cardioverter defibrillators, a computed tomography (CT ) scan may be a safer imaging tool. (The devices may malfunction during an MRI scan).|
When your doctor orders an MRI it's because they are looking for something very specific—something that is either too small, too intricate or too subtle to be detected by other imaging technologies. An MRI allows us to view portions of the body with clarity and in precise areas. MRIs are different than many other types of imaging because an MRI does not use radiation.
Having an MRI is a relatively simple, non-invasive procedure. The machine itself is a large cylinder with a bed that slides into it. You will lie on the bed and we will position you within the machine and take the images we need. You will need to lie very still (expect to hear "hold your breath" a few times). Please read the guidelines below to acquaint yourself with the process.
Our staff will work with you to ensure that you are comfortable throughout the process.
Talk with your physician and with our staff to make certain your questions are answered before your MRI at Mat-Su Regional Medical Center. Here is some general information about your MRI:
- No metal (earrings, belt buckles, watches, etc.) is allowed in the MRI. There is a locker room where you may store metal objects.
- The MRI machine is a bit noisy. There is a hum and a clicking sound. This is normal. Depending on the type of exam, you may be offered headphones with a choice of music or ear plugs.
- An MRI can last less than an hour. People who suffer from claustrophobia should practice relaxation techniques which our staff can help you with.
- The MRI staff will talk with you over an intercom system, but the voice that says "please hold your breath" and "you may breathe" is a computerized voice.
- Please don’t hesitate to ask questions throughout the procedure.
- There is a waiting area for your family outside the MRI room.
- Results will be sent to your physician. You should expect to receive results from your physician at a follow up visit.
