Widespread use of MRI (magnetic resonance imaging) has revolutionized the ability to diagnose multiple sclerosis. Disease-related changes in the brain or spinal cord are detected by MRI in more than 90% of people suspected of having MS.
What Is MRI?
MRI is a test that produces very clear pictures of the human body without the use of X-rays. It uses a large magnet, radio waves and a computer to produce these images.
Why Do I Need to Get an MRI?
- To detect MS. MRI is considered the best test to help diagnose MS. However, 5% of people with MS do not have abnormalities detected on MRI; thus, a “negative” scan does not completely rule out MS. In addition, some common changes of aging may look like MS on a MRI.
- To track the progress of disease. Although they aren’t widely needed, people with MS may get repeat scans to determine the status of their disease and how well their medications are working.
Is the MRI Exam Safe?
Yes. The MRI exam poses no risk to the average person if appropriate safety guidelines are followed. Many people who have had heart surgery and people with the following medical devices can be safely examined with MRI (the metals used in these surgeries are not “magnetic” and the person can be safely placed in the MRI machine):
- Artificial joints
- Staples
- Many cardiac valve replacements (check with your doctor)
- Disconnected medication pumps
- Vena cava filters
- Brain shunt tubes for hydrocephalus
Some conditions may make an MRI exam a bad idea. Tell your doctor if you have any of the following conditions:
