Clinical outcomes of patients with acute ischemic stroke depend in part on the extent of their
collateral circulation. A good collateral circulation has also been associated with greater …

Background and purpose Among patients with an acute ischaemic stroke secondary to large‐
vessel occlusion, the hypoperfusion intensity ratio (HIR)[time to maximum (TMax)> 10 …

Background and Purpose: Acute ischemic stroke (AIS) is a serious threat to the life and
health of middle-aged and elderly people. Mechanical thrombectomy offers the advantages …

Despite improved treatment, a large portion of patients with acute ischemic stroke due to a
large vessel occlusion have poor functional outcome. Further research exploring novel …

Abstract Digital Subtraction Angiography (DSA) is the gold-standard imaging modality in
acute cerebrovascular diagnosis. The role of DSA has become increasingly prominent since …

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 …

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

Precise imaging is essential for the accurate diagnosis and surgical guidance of brain
diseases but it is challenging due to the difficulties in crossing the blood-brain barrier (BBB) …

Background and Purpose—Previous studies suggest that intracranial carotid artery
calcification (ICAC) volume might influence the clinical outcome of patients after …

Collateral status has prognostic and treatment implications in acute ischemic stroke (AIS)
patients. Unlike CTA, grading collaterals on MRA is not well studied. We aimed to evaluate …
