Magnetic resonance imaging was used to evaluate the cerebral white matter of three subject groups: ( I ) 22 patients with known multiple sclerosis (MS) (1 1 with disease of shorter duration (0-5 years) and 11 with disease of longer duration (>5 years)); (2) 9 patients with suspected MS; and (3) 12 n
In vivo measurement of T2 relaxation times in multiple sclerosis (MS) lesions by magnetic resonance imaging (MRI) is potentially useful for the evaluation of the disease activity. Seven patients with definite MS were investigated over a period of three years (19 examinations), using a whole-body MRI
