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: Cerebral artery stenosis or occlusion is the most common
etiological factor in patients with acute cerebral ischemia, but the rate of early diagnosis is …

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

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 …

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: Although digital subtraction angiography (DSA) provides
excellent visualization of the intracranial vasculature, it has several limitations. Our purpose …

ABSTRACT Background and Purpose. This study was designed to assess the accuracy of
transcranial color‐coded sonography (TCCS) as compared to magnetic resonance …

Background and Purpose—Digital subtraction angiography (DSA) is regarded as the gold
standard in assessing degree of stenosis in intracranial vessels. However, it is invasive and …

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 …
