BACKGROUND AND PURPOSE: Collateral flow is associated with clinical outcome after
acute ischemic stroke and may serve as a parameter for patient selection for intra-arterial …

BACKGROUND AND PURPOSE: Collateral blood flow is an important prognostic marker in
the acute stroke situation but approaches for assessment vary widely. Our aim was to …

BACKGROUND AND PURPOSE: Many studies have emphasized the relevance of collateral
flow in patients presenting with acute ischemic stroke. Our aim was to evaluate the …

Background and Purpose—Our aim was to determine the relationships between
angiographic collaterals and diffusion/perfusion findings, subsequent infarct growth, and …

BACKGROUND AND PURPOSE: In proximal anterior circulation occlusive strokes, collateral
flow is essential for good outcome. Collateralized vessel intensity in TOF-and contrast …

Background and Purpose—Status of collateral circulation is a strong predictor of outcome
after acute ischemic stroke. Our aim was to compare the predictive value of strategies for …

Background and Purpose—The study aims to determine whether volume transfer constant
(Ktrans) maps calculated from first-pass perfusion computed tomographic data are a …

Objective Dedicated magnetic resonance (MR) imaging (MRI) sequences for evaluation of
collaterals can be generated using MR perfusion (MRP) source data. We compared a novel …

Background and Purpose—Collateral flow plays an important role in maintaining tissue
viability in proximal large vessel occlusion. We developed and tested a regional …

Background: Assessing collateral status is important in acute ischemic stroke. The purpose
of this study was to compare multiphasic perfusion computed tomography (MPCT) with …
