BACKGROUND AND PURPOSE: Intracranial collaterals influence the prognosis of patients
treated with intravenous tissue plasminogen activator in acute anterior circulation ischemic …

Purpose Multiple scores have been described for the assessment of collateralization in
acute ischemic stroke. Currently, there is no gold standard for collateral assessment by CT …

Objective: We compared intracranial collaterals on pretreatment and day 2 brain CT
angiograms (CTA) to assess their evolution and relationship with functional outcomes in …

BACKGROUND AND PURPOSE: Good CTA collaterals independently predict good
outcome in acute ischemic stroke. Our aim was to evaluate the role of collateral circulation …

Objective To compare assessment of collaterals by single-phase computed tomography
(CT) angiography (CTA) and CT perfusion-derived 3-phase CTA, multiphase CTA and …

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—In acute ischemic stroke, large early infarct size estimated by the
Alberta Stroke Program Early CT Score (ASPECTS) is associated with poorer outcomes and …

Background and Purpose—The role of noninvasive methods in the evaluation of collateral
circulation has yet to be defined. We hypothesized that a favorable pattern of …

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 status is an important factor determining outcome in
acute ischemic stroke (AIS). Hence, different collateral scoring systems have been …
