BACKGROUND AND PURPOSE Plaque formation at arterial bifurcations depends on vessel anatomy, particularly the relative sizes of the branches, and the ratio of the outflow to inflow area. The facts that carotid plaque is more common in men and that carotid bruits in the absence of stenosis are more frequent in women raise the possibility that there are sex differences in carotid bifurcation anato...

To evaluate the limitations of intravenous carotid digital subtraction angiography (DSA) in the diagnosis of carotid disease, studies of 130 patients were reviewed. Factors that resulted in a nondiagnostic study included: (1) misregistration larynx artifact overlying the carotid bifurcation; (2) external carotid or vertebral artery overlying the internal carotid artery; and (3) poor arterial co...

Carotidynia is an idiopathic syndrome characterized by pain over the carotid bifurcation without associated luminal pathologic process. The classification of carotidynia as a distinct disease rather than as a symptom has generated controversy in the literature. Recent reports, however, suggest that carotidynia is a distinct disease characterized by the presence of enhancing soft tissue in the c...

Background Multilevel significant atherosclerotic disease involving the carotid bifurcation and the proximal ipsilateral common carotid or brachiocephalic arteries presents an uncommon and difficult management problem. Axial (aortocarotid bypass) or extra-anatomic procedures (subclavian–carotid bypass, carotid–carotid bypass, carotid–subclavian transposition) and variations in the performance o...

Oculoplethysmography-carotid phonoangiography and periorbital directional Doppler sonography are two techniques widely used in the noninvasive evaluation of possible carotid artery disease. Recent advances with sonographic Doppler devices now permit measurement of blood velocities in the extracranial carotid arteries by direct scanning with a color coded Doppler imaging system. A prospective st...

BACKGROUND Cerebral emboli resulting from atherosclerosis at the carotid bifurcation is a major cause of ischemic stroke. A convenient and prompt evaluation is necessary for secondary prevention and treatment. METHODS In this study, one hundred and thirty eight patients with cerebral ischemic events were enrolled; 100 patients with nonischemic cerebral diseases were enrolled as controls. Noni...

permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Previous studies have reported stroke magnetic resonance imaging (MRI) assessments that included a carotid magnetization-prepared rapid acquisition with gradient-echo (MPRAGE) sequence. The findings of these studies showed that a carotid MPRAGE-positive signal was...

Using carotid bifurcation phantom models with different degrees of stenoses, we evaluated the accuracy of vessel lumen representation on MR images obtained from the inverse Fourier transform of different k-space percentages. Our results show that the lower thresholds of truncated k-space sampling are dictated by the severity of luminal narrowing. The defined thresholds may help improve efficien...
