How can MRIs be used to monitor and diagnose multiple sclerosis (MS)?

Multiple Sclerosis Foundation

Magnetic resonance imaging (MRI) can be a very useful tool in diagnosing and monitoring multiple sclerosis (MS). New MS lesions will typically "enhance" with dye for about six weeks. MS lesions older than six weeks or so will no longer enhance, but will still leave behind a bright white area on certain MRI images. The typical person with relapsing-remitting MS who is not on any treatment will have an enhancing lesion on brain MRI about 50 percent of the time.

Multiple Sclerosis Diagnosis

Diagnosing multiple sclerosis (MS) can be done with magnetic resonance imaging (MRI), evoked potential tests, in which electrodes are placed on the head and body, and neurological exams. The disease can be harder to diagnose in children since they may not be able to describe their sensory symptoms, or the symptoms may be similar to those of other neurological diseases.
