CT angiography is a widely used technique for the noninvasive evaluation of neurovascular
pathology. Because CTA is a snapshot of arterial contrast enhancement, information on flow …

The evaluation and management of acute ischemic stroke has primarily relied on the use of
conventional CT and MRI techniques as well as lumen imaging sequences such as CT …

Background and Purpose—Preclinical studies showed that thrombi can be permeable and
may, therefore, allow for residual blood flow in occluded arteries of patients having acute …

Background and Purpose—In patients with symptomatic intracranial atherosclerotic
stenosis, identifying the underlying stroke mechanisms may inform secondary prevention …

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 …

Background and purpose To evaluate whether brain CT perfusion (CTP) aids in the
detection of intracranial vessel occlusion on CT angiography (CTA) in acute ischemic stroke …

Background and Purpose—The length of large vessel occlusion is considered a major factor
for therapy in patients with ischemic stroke. We used 4D-CT angiography evaluation of …

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 …

Background and Purpose—Preclinical studies showed that thrombus permeability improves
recombinant tissue-type plasminogen activator (r-tPA) efficacy. We hypothesize that …

BACKGROUND AND PURPOSE: Collateral status and thrombus length have been
independently associated with functional outcome in patients with acute ischemic stroke. It …
