BACKGROUND AND PURPOSE: Large admission DWI lesion volumes are associated with
poor outcomes despite acute stroke treatment. The primary aims of our study were to …

Background Malignant profiles were identified by imaging profiles and unfavorable
outcomes that have poor response to reperfusion therapy. Many trials have used this profile …

Background and Purpose—Diffusion-weighted imaging (DWI) Alberta Stroke Program Early
CT Score (ASPECTS), a surrogate of infarct volume, predicts outcome in anterior large …

Background Understanding ischemic core growth rate (IGR) is key in identifying patients
with slow-progressing large vessel occlusion (LVO) stroke who may benefit from delayed …

Background and Purpose: We aim to examine effects of collateral status and post-
thrombectomy reperfusion on final infarct distribution and early functional outcome in …

Background and Purpose—Diffusion-weighted imaging (DWI) lesion volume is associated
with poor outcome after thrombolysis, and it is unclear whether endovascular therapies are …

Background and Purpose—Ischemic lesion volume (ILV) assessed by follow-up noncontrast
computed tomography correlates only moderately with clinical end points, such as the …

Objectives To compare collateral status on single-phase CT angiography (sCTA) and
multiphase CT angiography (mCTA) and their ability to predict a target mismatch on CT …

Background and Purpose—Lesion volume on diffusion-weighted magnetic resonance
imaging (DWI) before acute stroke therapy is a predictor of outcome. Therefore, patients with …

Background The degree of variability in the rate of early diffusion-weighted imaging
expansion in acute stroke has not been well characterized. Aim We hypothesized that …
