MRI (magnetic resonance imaging) uses a magnetic field and radio waves to create detailed images of the brain and spinal cord. It can help detect changes that may be related to Sjögren’s disease or other neurologic conditions.
The test is painless and requires you to lie still on a padded table while the machine takes images. The table will move slowly through the scanner, and the test usually takes about 45 to 60 minutes. In some cases, a contrast dye may be injected into a vein to make the images clearer.
The MRI images are reviewed along with your symptoms, exam, and other test results.
Important: MRI may not be safe and is best avoided if you have certain implanted devices or metal in your body, such as a pacemaker, aneurysm clips, or metal fragments. Be sure to tell your doctor if you have any of these.
