BACKGROUND AND PURPOSE: Various Doppler criteria have been used to predict
hemodynamically significant carotid stenosis. This study was performed to elucidate whether …

Objective Blood flow velocity criteria in the diagnosis of carotid stenosis are well defined;
however, there are no reference values concerning blood flow volume. The objective of this …

PURPOSE: We investigated whether measurement of blood flow in the extracranial distal
internal carotid artery (ICA) by transoral carotid ultrasonography (TOCU) can predict the …

Background. Common carotid artery (CCA) volume flow rate (VFR) is clinically useful for
study of cerebrovascular disease. Color Velocity Imaging Quantification (CVI‐Q; Philips …

BACKGROUND AND PURPOSE: In severe carotid stenosis, blood supply via the
poststenotic internal carotid artery (ICA) and collateral pathways determine cerebral …

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

The ratio between the systolic peak velocities of the internal and common carotid arteries
(vpICA/vpCCA), vpICA and grey-scale imaging measurement are generally used to evaluate …

Purpose: The accuracy of duplex sonography in predicting the degree of an internal carotid
artery (ICA) stenosis is decreased when a contralateral high-grade stenosis or occlusion is …

Objectives We compared internal carotid artery Doppler peak systolic velocities (PSVs)
measured with angle correction parallel to the artery wall (//wall) on grayscale images and …

Purpose: The driving force for blood flow through a high-grade stenosis in the internal
carotid artery can be expressed as the pressure gradient over the stenosis itself, which …
