MR imaging in XXXX : comparison with clinical, @entity2841 , and visual evoked potential findings.

@entity1 @entity854 @entity2841 @entity15
MR examinations of 136 @entity1 with @entity15 ( @entity15 ) were evaluated to correlate the results with clinical, @entity2841 , and visual evoked potential (VEP) findings. In addition, 22 of the 136 @entity1 were studied several times during a 5-month follow-up period. It was demonstrated that MR is superior to @entity2841 findings in establishing cerebral alterations in @entity15 . A relationship between the results of @entity2841 examinations and the MR results could not be detected. Negative @entity2841 results corresponded to positive MR imaging and vice versa. In our series, five negative MR results were obtained in @entity1 with clinically proved @entity15 . The extent of alterations shown up by MR corresponds to the duration of the disease; in particular, more @entity854 in the periventricular region were found in @entity1 with long-standing disease. More plaques were found in @entity1 with a primary relapsing/remitting course of the disease than with the primary chronic progressive form. The clinical course and the grade of disability did not correspond to differences in MR imaging. Follow-up demonstrated that most lesions remain unchanged (72-79%); increases and decreases in the size of the plaques seem to depend on the clinical course. These results suggest that MR is the most sensitive technique for establishing the diagnosis of @entity15 .
