Column labeled T2* signal indicates hemorrhagic (Y) or ischemic (N) presumed CVA. Column labeled EPI indicates if echo planar (Y) or non-echo planar (N) diffusion-weighted imaging was used. Duration of clinical signs is the number of days elapsed between the onset of neurological signs and MRI. Because ADC values were only analyzed for those image sets that had T2-FLAIR hyperintensity on MRI, hemorrhagic presumed CVAs with no T2-FLAIR hyperintensity do not have ADC values.
