The percentage of diameter stenosis of the internal carotid artery was estimated directly from
color Doppler images obtained in both longitudinal and transverse planes and compared …

Carotid artery disease was assessed in 180 patients by means of color Doppler flow
imaging. Color Doppler findings in 360 carotid arteries were compared with the results of …

The purpose of this study was to evaluate and compare the accuracies of the different
Doppler velocity parameters used to grade stenoses of the carotid artery. Seven velocity …

PURPOSE: To examine the variability of Doppler measurements along the extracranial
courses of the nondiseased common carotid artery (CCA) and internal carotid artery (ICA) …

PURPOSE: To determine if Doppler ultrasound (US) measurements of systolic velocity in the
common carotid artery vary markedly with distance from the bifurcation. MATERIALS AND …

The purpose of this study was to prospectively compare CT angiography with conventional
angiography for detecting stenosis at the carotid bifurcation. Thirty-five patients referred for …

PURPOSE: To determine the effect of variability of common carotid arterial (CCA) velocities
on velocity ratios used to assess internal carotid arterial (ICA) stenosis. MATERIALS AND …

The accuracy, rapidity, and reproducibility of color-Doppler-assisted duplex sonography in
the diagnosis of significant internal carotid artery stenosis were prospectively evaluated …

Background: Duplex ultrasound with Doppler velocimetry is widely used to evaluate the
presence and severity of internal carotid artery stenosis; however, a variety of velocity …

The degree of internal carotid stenosis has emerged as the most important predictor of
ischemic stroke in extracranial carotid artery disease. The purpose of this study was to …
