WebDWI-FLAIR mismatch was defined when a visible acute ischemic lesion was present on DWI without traceable parenchymal hyperintensity on FLAIR. Image analysis was done by 2 stroke neurologists independently. WebThe MRI sequences included conventional T2, FLAIR and DWI on axial view (DWI performed for 51% of all patients), from medulla to cortex, at 5 mm section thickness. All MR studies were reviewed by a neuroradiologist and a neurologist. The examiners looked specifically for hyperintense lesions on FLAIR or DWI. The number and location of …
