PURPOSE: To determine if duplex ultrasonography (US) can help predict the degree of
internal carotid arterial (ICA) stenosis. MATERIALS AND METHODS: ICA peak systolic …

There is no standard classification for quantifying the degree of internal carotid artery
stenoses by means of Doppler sonography. Above all this requires a clear concept of how to …

Purpose: The Asymptomatic Carotid Atherosclerosis Study, demonstrating the benefit of
carotid endarterectomy for symptom-free patients with 60% or greater carotid artery stenosis …

Ever since carotid stenosis measurements were developed to aid randomized clinical trials
of carotid endarterectomy, a single number was introduced as an index of the disease …

PURPOSE Accurate calculation of the percentage of stenosis is crucial for identifying
candidates for endarterectomy. Our goal was to quantify the reduction in diameter of the …

Results The PSV in the stenoses between 40-50% presents more than 1 standard deviation
(SD) above the mean. There were no significant deviations in other degrees of stenosis (p> …

BACKGROUND/PURPOSE: Identification of carotid near-occlusion is essential before
calculation of percent stenosis because stroke risk is lower than other severe stenosis and …

BACKGROUND AND PURPOSE: To compare multisection CT angiography (CTA) analyzed
with source/maximum intensity projection (MIP) images as well as semiautomated vessel …

Background and Purpose—We hypothesized that direct cervical investigation with Power M-
Mode Doppler (PMD) combined with single-gate Doppler spectral analysis (SGDSA) using a …

We evaluated the ability of transcranial Doppler ultrasonography (TCD) of the middle
cerebral artery to detect internal carotid artery luminal area stenosis of 70% or greater by …
