Carotid artery disease assessed by color Doppler flow imaging: correlation with standard Doppler sonography and angiography.
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 standard Doppler sonography, and color Doppler findings in 60 bifurcations were compared with the results of intraarterial angiography. The sensitivity of color Doppler for the detection of carotid disease was 100% when comp...
متن کاملDuplex and color Doppler flow sonography of occlusion and near occlusion of the carotid artery.
PURPOSE To determine whether color Doppler flow imaging with the use of slow-flow sensitivity improves sensitivity and specificity in the differentiation of occlusion and near occlusion of the internal carotid artery. METHODS Color Doppler and duplex sonography were performed in symptomatic patients who had angiographically confirmed occlusion and/or near occlusion of the internal carotid art...
متن کاملThree-dimensional color Doppler sonography in carotid artery stenosis.
BACKGROUND AND PURPOSE Color Doppler sonography (CDS) suffers from such disadvantages as high interobserver variability and problems with data presentation and storage. We therefore performed a prospective trial to assess the role of three-dimensional CDS (3D-CDS) in the evaluation of internal carotid artery stenosis (ICAS). METHODS We included 32 consecutive patients with sonographically ver...
متن کاملHigh-Grade Internal Carotid Stenosis With Color Doppler-Assisted Duplex Imaging
Background and Purpose The remaining limitations of ultrasonographic imaging in accurately quantifying internal carotid stenosis or diagnosing internal carotid occlusion may be overcome by enhancing the echogenicity of flowing arterial blood with contrast agents. This study assessed the usefulness of the intravenous (transpulmonary) contrast medium SH U 508 A in improving the characterization a...
متن کاملDiagnosis of internal carotid artery stenosis greater than 70% with power Doppler duplex sonography.
BACKGROUND AND PURPOSE Duplex sonography is an effective tool for evaluating internal carotid artery (ICA) stenosis, and power Doppler imaging has improved its value in this regard. Our goal was to elucidate which parameters, such as linear stenosis, area stenosis, and peak systolic velocity (PSV), are the most reliable predictors of ICA stenosis greater than 70% using the method proposed by th...
