Purpose: To prospectively determine, for both digital subtraction angiography (DSA) and
contrast material–enhanced magnetic resonance (MR) angiography, the accuracy of …

Purpose To compare easy-to-perform three-dimensional power Doppler ultrasound (3D
PDUS) to color Doppler ultrasound (CDUS) and digital subtraction angiography (DSA) in the …

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 …

Objectives The aim of this retrospective study was to compare intracranial arterial stenosis in
patients with stroke using 3 different methods: transcranial color‐coded duplex sonography …

BACKGROUND AND PURPOSE: Although digital subtraction angiography (DSA) is the
reference standard for assessing carotid arteries, it is uncomfortable for patients and has a …

ABSTRACT BACKGROUND Transcranial Doppler (TCD) is widely applied to evaluate the
intracranial large artery stenosis. We aimed to evaluate the accuracy of TCD in detecting …

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 …

Ultrasonography (US) of the carotid arteries is a common imaging study performed for
diagnosis of carotid artery disease. In the United States, carotid US may be the only …

Aim to investigate the importance of Doppler angle differentiating between 50–69% and≥
70% internal carotid artery (ICA) stenosis. Material and methods fifty-one patients with a …

The recently published clinical trials of carotid endarterectomy marked a turning point in
carotid sonography, because they provided justification for seeking carotid stenosis with …
