Background: Vertebrobasilar insufficiency (VBI) is a common cerebrovascular problem
caused by reduction of vertebral artery flow, from atherosclerotic and degenerative changes …

ABSTRACT BACKGROUND AND PURPOSE We sought to validate ultrasound as a reliable
means of assessing vessel stenosis of vertebral artery origins. METHODS We reviewed …

Background: Transcranial color-coded sonography (TCCS) is used as a real-time tool to
evaluate patients suspected of having vertebrobasilar insufficiency (VBI). However, the …

INTRODUCTION:: Vertebral artery hypoplasia (VAH) may be defined as VA flow volume
below≈ 30–40mL/min using color duplex sonography. The aim of this study was to evaluate …

Background and Purpose—Vertebral stenosis is associated with a high risk of recurrent
stroke, but noninvasive imaging techniques to identify it have lacked sensitivity. Contrast …

AIM To determine the optimal thresholds for assessing intervertebral segment stenosis
through haemodynamic parameters of colour Doppler ultrasound compared with computed …

The relationship between carotid atherosclerotic disease and lateralizing symptoms of
cerebrovascular ischemia, such as transient ischemic attacks, amaurosis fugax, and stroke …

INTRODUCTION:: The aim of this study was to compare the measurements of vertebral
artery (VA) systolic flow velocity and flow volume for diagnosis of vertebrobasilar …

Objective. The aim of the study was to assess the potential of 3‐dimensional (3D) color‐
