BACKGROUND AND PURPOSE: We sought to assess whether contrast-enhanced MR
angiography is able to predict the degree of angiographic stenosis of the internal carotid …

Background and Purpose—The purpose of this work was to review and compare published
data on the diagnostic value of duplex ultrasonography (DUS), MR angiography (MRA), and …

Background and Purpose There is a clinical imperative for noninvasive tests for carotid
disease that have high sensitivity. Previous studies have shown that transcranial Doppler …

Background The standard techniques for the screening and staging of internal carotid artery
(ICA) stenosis are Doppler (continuous wave) and Duplex sonography. For the imaging of …

BACKGROUND AND PURPOSE: Intracranial large-artery atherosclerosis is considered a
frequent cause of stroke worldwide, particularly in Asian populations. The current evidence …

BACKGROUND AND PURPOSE: MR angiography (MRA) is increasingly used as an
alternative to digital subtraction angiography (DSA) to evaluate internal carotid artery (ICA) …

PURPOSE: Carotid artery stenosis quantification uses percent diameter ratios from
conventional angiography. Multidetector high-speed CT angiography (CTA) allows direct …

ABSTRACT Background and Purpose. This study was designed to assess the accuracy of
transcranial color‐coded sonography (TCCS) as compared to magnetic resonance …

ABSTRACT BACKGROUND AND PURPOSE The aim of this study is to assess contrast‐
enhanced transcranial color‐coded duplex sonography (CE‐TCCS) diagnosis of basilar …

We performed a preliminary study comparing three-dimensional time-of-flight (3 D TOF)
magnetic resonance angiography (MRA) and spiral CT angiography (SCTA) in the detection …
