Hemodynamic changes may provide important information for clinical decision‑making in
internal carotid artery (ICA) stenosis. The degree of stenosis is responsible for the …

BACKGROUND AND PURPOSE: Contrast-enhanced MR angiography and extracranial
color-coded duplex sonography are noninvasive, preoperative imaging modalities for …

Background: Intracranial atherosclerotic stenosis is a common cause of ischemic
cerebrovascular events and is associated with a high risk of stroke recurrence. This study …

BACKGROUND AND PURPOSE: Gradation of high-grade intracranial internal carotid artery
(ICA) stenosis poses a challenge to noninvasive neurovascular imaging, which seems …

Objective The purpose of this study was to validate the accuracy and criteria of transcranial
color‐coded sonography (TCCS) in detecting severe middle cerebral artery (MCA) stenosis …

Purpose: The accuracy of duplex sonography in predicting the degree of an internal carotid
artery (ICA) stenosis is decreased when a contralateral high-grade stenosis or occlusion is …

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 …

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: According to the data from the population-based Rotterdam study, intracranial
carotid artery calcification detected by computed tomography is very common and …

Atherosclerotic stenoses of the intracranial vessels are less frequent than those of the
extracranial vessels, but they are associated with a considerable annual stroke rate. The aim …
