BACKGROUND AND PURPOSE: Gradation of high-grade intracranial internal carotid artery
(ICA) stenosis poses a challenge to noninvasive neurovascular imaging, which seems …

Objectives The aim of this retrospective study was to compare intracranial arterial stenosis in
patients with stroke using 3 different methods: transcranial color‐coded duplex sonography …

Background and Purpose—A favorable risk-benefit ratio for warfarin compared with aspirin
has been reported for the prevention of major vascular events in symptomatic≥ 50 …

BACKGROUND AND PURPOSE: Duplex sonography is an effective tool for evaluating
internal carotid artery (ICA) stenosis, and power Doppler imaging has improved its value in …

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 …

Atherosclerotic stenoses of the intracranial vessels are less frequent than those of the
extracranial vessels, but they are associated with a considerable annual stroke rate. The aim …

Objective The purpose of this study was to validate the accuracy and criteria of transcranial
color‐coded sonography (TCCS) in detecting severe middle cerebral artery (MCA) stenosis …

BACKGROUND AND PURPOSE: Color Doppler sonography (CDS) suffers from such
disadvantages as high interobserver variability and problems with data presentation and …

BACKGROUND AND PURPOSE: Contrast-enhanced MR angiography and extracranial
color-coded duplex sonography are noninvasive, preoperative imaging modalities for …

Background and purpose. We initiated this prospective study to investigate the usefulness of
contrast enhancement in combination with color Doppler-assisted duplex imaging (CDDI) for …
