Magnetic resonance imaging (MRI) can be an important tool in the diagnosis of multiple sclerosis (MS). MRI can also be used to monitor the progression of the disease in people living with MS.
MRI uses very strong magnets, radio signals, and computer software to take pictures of the inside of the body.
Maybe. Contrast material is a substance that temporarily changes the way imaging tools interact with the body. They are often used to visualize certain types of MS disease activity on the MRI. If your healthcare provider thinks your scan requires this contrast material, you may get an injection before you get in the MRI machine.
An MRI test lasts anywhere from 20 to 60 minutes, but may take longer. Be sure to discuss with your healthcare provider in advance so he or she can provide you with exact timing.

The actual device emits a very unique sound. It might surprise you if you don’t know it’s coming. Talk to the technician as he or she can help you understand what to expect. It’s a sort of “Ca-CHUNK, Ca-CHUNK.” Don’t worry: it’s normal. The technician will probably warn you about the sound as well.
It may also seem a little cramped in the machine. If you suffer from claustrophobia, let your healthcare provider know. He or she may have suggestions for how to deal with your discomfort.
It’s important to work with your primary healthcare provider when scheduling an MRI and reviewing the results. Typically, your primary healthcare provider will schedule an appointment to review both the written report and the actual images from the scan. As these scans become more routine, you may not always meet in person to discuss the results. It’s important to note that the technician who runs the MRI machine won’t be able to give you any information on the day of the scan. Only your healthcare provider can interpret your results, so ask your healthcare provider if you don’t understand something.
