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 …

Objective In the real-world practice of endovascular thrombectomy (EVT) for acute ischemic
stroke (AIS), the analysis of intraprocedural angiographic signs (IPASs) still challenges …

Background and Purpose—The Mechanical Embolus Removal in Cerebral Ischemia
(MERCI) and Multi MERCI trials evaluated the safety and efficacy of thrombectomy in the …

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: Although recanalization is the goal of thrombolysis, it is
well recognized that it fails to improve outcome of acute stroke in a subset of patients. Our …

As expected, patients with acute ischemic stroke typically present with a perfusion deficit (ie,
low-to-absent ASL CBF signal) in the affected region (Figure 1). Depending on the precise …

BACKGROUND AND PURPOSE: In patients with acute stroke, the location and extent of
intravascular thrombi correlate with clinical and imaging outcomes and have been used to …

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

Background and Purpose—Thrombolysis depends on the ability of blood and thrombolytic
agents to permeate thrombus. We devised a novel technique to quantify blood permeating …

Background and Purpose—In acute stroke patients with intracranial vessel occlusion,
angiographic demonstration of antegrade contrast opacification distal to the occlusion site …
