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 …

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

Purpose It has been reported that the extent of intravascular thrombi and the quality of
collateral filling in computed tomography (CT) angiography are predictive for the clinical …

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—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 vessel status is strongly associated with clinical
outcome in ischemic stroke but can be challenging to assess. The aim of this study was to …

Objectives In acute stroke patients with large vessel occlusion, collateral blood flow affects
tissue fate and patient outcome. The visibility of collaterals on computed tomography …

Purpose The collateral status can be defined not only by its morphological extent but also by
the velocity of collateral filling characterized by the relative filling time delay (rFTD). The aim …

BACKGROUND AND PURPOSE: Multiphase CTA, a technique to dynamically assess the
vasculature in acute ischemic stroke, was primarily developed to evaluate collateral filling …
