Noninvasive color-coded duplex sonography has become a good, convenient, and
reproducible screening tool for the general population when studying cerebral …

Background and Purpose An understanding of carotid atherosclerosis is important to further
our knowledge regarding the etiology of cerebral ischemia, and therefore it is necessary to …

Carotid duplex ultrasonography is a common noninvasive technique for evaluating cases of
suspected extracranial carotid artery occlusive disease. This manuscript describes the …

SUMMARY∑ The development of duplex ultrasound instrumentation combining high-
resolution B-mode imaging with Doppler flow analysis represents a major advancement in …

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 …

Carotid duplex ultrasonography (CDU) is noninvasive and easy to use for evaluation of
various carotid artery diseases. Carotid atherosclerosis is a major indication for CDU. CDU …

Atherosclerotic lesions of the extracranial cerebral arteries account for ischemic stroke in
over half of all cases. The risk of stroke associated with symptomatic carotid artery disease is …

We prospectively compare duplex-ultrasonography with angiographic methods in the
evaluation of extracranial carotid atherosclerosis. The degree of stenoses is divided into five …

Duplex sonography is an accurate method for evaluating the cervical carotid arteries. We
feel it is the method of choice for screening asymptomatic patients or those with …

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