Overview
MRI
On MRI, multiple sclerosis is characterized by cerebral and/or spinal cord plaques which are demyelinating areas.
Magnetic resonance imaging (MRI) of the brain and spine is often used during the diagnostic process. MRI shows areas of demyelination (lesions) as bright spots on the image. A substance, called Gadolinium, can be injected into the spinal column to highlight active plaques and, by elimination, demonstrate the existence of historical lesions not associated with clinical symptoms. This can provide the evidence of chronic disease needed for a definitive diagnosis of MS.
