Abstract: To quantitatively evaluate the volume of the ischemic penumbra using susceptibility-weighted imaging and mapping (SWIM) of asymmetrical prominent cortical veins (APCVs) in patients with acute ischemic stroke. Eighty-five eligible patients with acute ischemic stroke on… read more here.

Abstract: Background: Two imaging paradigms, the diffusion-weighted imaging (DWI) - fluid attenuated inversion recovery (FLAIR) and perfusion-weighted imaging (PWI) - DWI mismatch, used in the Efficacy and Safety of MRI-Based Thrombolysis in Wake-Up Stroke (WAKE-UP) and… read more here.

FLAIR Vascular Hyperintensities as a Surrogate of Collaterals in Acute Stroke: DWI Matters

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.
