OBJECTIVES: Modern conventional ultrasound is sensitive to slow flow, but may misclassify
some tight stenoses as occlusion. Symptomatic patients with tight proximal internal carotid …

Objective: The purpose of this study was to evaluate the use of an echo-enhancing agent in
patients with carotid artery occlusion to improve the sensitivity and specificity of carotid color …

It remains a significant technical challenge for duplex ultrasound to accurately differentiate
between total and near total internal carotid artery (ICA) occlusions. We have evaluated the …

PURPOSE: To evaluate ultrasonography (US) and magnetic resonance (MR) angiography
in the differentiation between occlusion and near occlusion of internal carotid artery (ICA) …

Background: To investigate the accuracy of conventional carotid ultrasonography (CCU)
combined with transoral carotid ultrasonography (TOCU) for distinguishing pseudo …

To determine the diagnostic accuracy of extracranial internal carotid artery (ICA) occlusion
by carotid duplex sonography and ophthalmic flow direction, we compared both carotid …

Background and Purpose—Our study evaluated noninvasive tests for the diagnosis of
atheromatous internal carotid artery (ICA) pseudo-occlusion. Methods—Twenty patients (17 …

OBJECTIVE: The purpose of this study was to evaluate the effectiveness of contrast-
enhanced ultrasound with a second-generation contrast agent in distinguishing between …

Background and purpose: Color duplex ultrasound has been advocated as an alternative to
arteriography before carotid endarterectomy. However, one limitation of color duplex …

Purpose: Duplex ultrasonography is an accurate, noninvasive method for diagnosing,
characterizing, and classifying atherosclerotic stenoses of the extracranial carotid artery …
