Plaque Burden Measurement by Black-blood MR Imaging Technique in Intracranial and Extracranial Carotid Arteries in Acute Stroke Patients
نویسندگان
چکیده
Introduction: Concurrent atherosclerosis of the intracranial and extracranial cerebrovascular system is common in Asians . Atherosclerotic diseases occurring in carotid arteries and intracranial arteries have been demonstrated to be associated transient ischemic attack (TIA) and stroke . Recently, Black-blood magnetic resonance imaging (MRI) has been increasingly applied for assessment of the carotid artery and intracranial vessel wall . However, measure of plaque burden in intracranial and extracranial carotid arteries at the same individual by black-blood MRI and its association have not been determined. To investigate these correlations will be helpful for better understanding the heterogeneity of disease progression in these two vascular territories and potentially improving the predictive value for cerebrovascular events.

BACKGROUND As a systemic disease, atherosclerosis commonly affects intracranial and extracranial carotid arteries simultaneously which is defined as co-existing plaques. Previous studies demonstrated that co-existing atherosclerotic diseases are significantly associated with ischemic cerebrovascular events. The aim of this study was to investigate the characteristics of co-existing intracranial...

BACKGROUND AND PURPOSE It has been shown that patients with a first ischemic stroke are at high risk of developing recurrent stroke due to carotid atherosclerotic plaque rupture. However, no one has defined the difference in plaques between initial and recurrent stroke. This study sought to investigate the characteristics of carotid plaque between patients with first-time and recurrent acute is...

The lowering of cholesterol with statins (3-hydroxy3-methylglutaryl coenzyme A reductase inhibitors) has shown protective effects against coronary, carotid, and intracranial artery atherosclerosis. Pleiotropic effects on atherosclerotic plaque stabilization in coronary and extracranial arteries have also been reported. Results from clinical trials support a significant decrease in vascular even...
