Radiologically Isolated Syndrome: MR Imaging Features Suggestive of Multiple Sclerosis Prior to First Symptom Onset.

Abstract

Remarkable advances in the understanding of the biology of multiple sclerosis have been achieved through the use of conventional and novel MR imaging techniques of the central nervous system. With improvements in access by patients and utilization of MR imaging technology in health care, an increasing number of unanticipated structural anomalies are being appreciated. In certain instances, white matter abnormalities within the brain and spinal cord are discovered in subjects with no prior history of neurologic symptoms supportive of inflammatory demyelinating events.
