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

The velocity of collateral filling can be assessed in dynamic time-resolved computed
tomography (CT) angiographies and may predict initial CT perfusion (CTP) and follow-up …

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

BACKGROUND AND PURPOSE: Dynamic CTA is a promising technique for visualization of
collateral filling in patients with acute ischemic stroke. Our aim was to describe collateral …

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—This study aimed to derive and validate an optimal collateral
measurement on computed tomographic perfusion imaging for patients with acute ischemic …
