summary: In certain clinical situations, the current diagnostic criteria for MS require a new MRI lesion compared with a reference scan performed at least 30 days after the onset of the symptoms. The authors studied whether a reference MRI performed sooner than this made any difference to the accuracy of the criteria. They concluded that new MRI lesions increased relapse risk regardless of the timing of the first scan.
