OBJECTIVE. The sonographic diagnostic criteria for vertebral artery stenosis have not been
fully investigated. The purpose of this study was to assess hemodynamic parameters at color …

The aim of this study was to compare the clinical value of vertebral artery ultrasound (VAU),
Magnetic Resonance Angiography (MRA) and Digital Subtraction Angiography (DSA) on …

The cervical vertebral arteries were visualized by real-time B-mode ultrasonography with
duplex Doppler in 595 consecutive patients. Comparison with angiography in 40 patients …

Objective. The appearance of the vertebral artery (VA) waveform on a pulsed Doppler
examination performed during standard carotid duplex ultrasonography (CDU) may suggest …

Background and Purpose—Atherosclerotic vertebrobasilar disease is an important cause of
posterior circulation stroke. To examine the role of hemodynamic compromise, a prospective …

Background and purpose: Posterior circulation stroke accounts for 20% of ischaemic
strokes. Recent data suggest that the early stroke recurrence risk is high and comparable …

Purpose The aim of this study was to evaluate the usefulness of vertebral artery (VA) pulsed
Doppler waveform changes in excluding basilar artery (BA) stenosis/occlusion. Methods …

Background The aim of the current study was to investigate whether signal intensities on
magnetic resonance imaging (MRI) views and radiological findings on Doppler …

ABSTRACT BACKGROUND Despite remaining an important cause of posterior circulation
stroke, the non‐invasive diagnosis of vertebral artery origin (VAo) stenosis is problematic …

Distinguishing stenosis and hypoplasia of the extracranial vertebral artery (VA) is clinically
important, but there is no agreement in defining VA hypoplasia. We endeavored to attain …
