ABSTRACT BACKGROUND AND PURPOSE The purpose of this study was to compare
Doppler ultrasound (DUS) to other angiographic modalities: computed tomography …

Introduction Most of the cases of ischaemic stroke in our setting are of atherothrombotic
origin. Detecting intracranial and cervical carotid artery stenosis in patients with ischaemic …

Physicians have been increasingly relying on noninvasive imaging methods to grade carotid
stenosis. The accuracy of Doppler ultrasound (DUS) and CT angiography (CTA) versus intra …

Introduction: Doppler ultrasound (DUS) is used as a screening tool to assess internal carotid
artery (ICA) disease. Recent reports suggest that the DUS may be inaccurate in over 28% of …

ABSTRACT Background and Purpose. We investigated the diagnostic performance of a brief
Power Doppler Imaging (PDI) screening examination for carotid artery stenoses using a …

Background and Purpose—Previous studies have suggested that patients with carotid
stenosis who are candidates for endarterectomy can be effectively identified on the basis of …

Background Atherosclerotic carotid disease represents approximately 20% of the causes of
ischemic stroke. Effective treatment options, such as endovascular or surgical …

Background and Purpose There is a clinical imperative for noninvasive tests for carotid
disease that have high sensitivity. Previous studies have shown that transcranial Doppler …

BACKGROUND AND PURPOSE: Doppler sonography of the carotid arteries is routinely
performed before catheter angiography, and its results may bias the subsequent …

Purpose Visualization of carotid artery stenosis is important to improve our understanding of
the etiology of ischemic stroke. Two sonographic methods are available for visualizing …
