Objectives Magnetic resonance angiography (MRA), three-dimensional computed
tomography angiography, and cerebral angiography may be used to assess intracranial …

Objectives Vertebrobasilar stenosis is frequent in patients with posterior circulation stroke
and it increases risk of recurrence. We investigated feasibility of duplex ultrasonography …

Background: Vertebrobasilar (VB) strokes appear to have the same causes as carotid
strokes. Obstructive lesions of proximal vertebral arteries probably occur in about 30% of …

Background and purpose A reliable and safe diagnostic procedure for vertebral artery (VA)
stenosis is needed, but none is generally accepted yet. In our study, we evaluated …

The aim of this study was to prospectively evaluate diffuse intracranial vertebrobasilar artery
stenosis by ultrasonic examination with digital subtraction angiography as the reference …

Background: The purpose of this study was to confirm whether the 3-dimensional
hemodynamics of the vertebrobasilar artery system can be evaluated using a combination of …

Background Currently, no clear diagnostic indicator of vertebral artery hypoplasia (VAH) or
intracranial stenosis exists in clinic. This study aims to study the feasibility of neck-brain …

Objectives The proximal segment of the vertebral artery is a frequent site of obstructive
atherosclerosis. The purpose of this study was to determine Doppler criteria for identifying …

Background and Objective Patients with symptomatic vertebral artery stenosis are at high
risk of stroke recurrence, especially≥ 70% stenosis. Revascularization may be considered …

Background Vertebral-basilar artery stenosis is associated with posterior circulation
infarction. So correct detection of vertebral basilar artery stenosis is very important. Studies …
