Subacute diffusion and ASL perfusion lesion and 8-week lasting infarction. Panel a displays a schematic illustration of infarct core with surrounding penumbra zone of perfusion restriction. Panel b illustrates the larger area of arterial spin labeling lesion with vivid cortical serpiginous hyperintensities (arterial transit artefact), surrounding a smaller DWI lesion (c). Panel d illustrates the permanent infarction lesion on the 8-week follow-up T2-FLAIR appearing in the same area as the DWI lesion
