Abstract: The authors evaluated 244 consecutive patients eligible for reperfusion therapy with MCA stroke and pretreatment MR imaging with both FLAIR and PWI. The FLAIR vascular hyperintensity score was based on ASPECTS, ranging from 0 (no… read more here.

DOI: 10.3174/ajnr.a7733
Abstract: BACKGROUND AND PURPOSE: FLAIR vascular hyperintensities are thought to represent leptomeningeal collaterals in acute ischemic stroke. However, whether all–FLAIR vascular hyperintensities or FLAIR vascular hyperintensities–DWI mismatch, ie, FLAIR vascular hyperintensities beyond the DWI lesion, best… read more here.
