Role of MR in Evaluating Multiple Sclerosis

Introduction: Multiple sclerosis is an inflammatory disease that attacks the central nervous system CNS (brain and spinal cord). Specifically, it attacks the myeline sheath of the neuron cells (1-3). Up to now there is no known pathophysiological cause of the MS disease but it is believed to be autoimmune. Autoimmune means the immunity system attacks normal tissues without obvious cause. It results in progressive neurological deficits leading to accumulating disabilities. The wide distribution of plaques (name of MS lesion) produces a variety of clinical symptoms.
