Correlation of Carotid Intraplaque Hemorrhage and Stroke Using 1.5 T and 3 T MRI
Carotid therosclerotic disease causes approximately 25% of the nearly 690,000 ischemic strokes each year in the United States. Current risk stratification based on percent stenosis does not provide specific information on the actual risk of stroke for most individuals. Prospective randomized studies have found only 10 to 12% of asymptomatic patients will have a symptomatic stroke within 5 years...

Correlation Between Carotid Intraplaque Hemorrhage and Clinical Symptoms To the Editor: In the systematic review by Gao et al about the correlation between intraplaque hemorrhage (IPH) and neurological symptoms in patients with carotid disease,1 the authors analyzed findings from 31 observational studies in order to determine the role of IPH as a predictor of cerebral ischemic events, and demon...
متن کاملCarotid artery intraplaque hemorrhage and stenotic velocity.
BACKGROUND AND PURPOSE One of the proposed mechanisms for sudden expansion of a carotid bifurcation plaque is hemorrhage within the lesion. It has been postulated that the sudden increase in plaque size will acutely reduce blood flow to the ipsilateral hemisphere and induce either a transient ischemic attack or a stroke. In this study, the relation between peak systolic velocity at the site of ...
متن کاملAdventitial perfusion and intraplaque hemorrhage: a dynamic contrast-enhanced MRI study in the carotid artery.
BACKGROUND AND PURPOSE Autopsy studies have suggested a relationship between intraplaque hemorrhage (IPH) and vasa vasorum, which arise primarily from the adventitia. Adventitial vasa vasorum can be characterized in the carotid arteries by estimating perfusion parameters via dynamic contrast-enhanced MRI. The purpose of this investigation was to use dynamic contrast-enhanced MRI to test in vivo...
متن کاملCorrelation between carotid intraplaque hemorrhage and clinical symptoms: systematic review of observational studies.
BACKGROUND AND PURPOSE We sought to investigate the association between carotid intraplaque hemorrhage (IPH) and ipsilateral symptoms of cerebral ischemia. METHODS A search was performed for clinical observational studies comparing the incidence of IPH between symptomatic and asymptomatic patients. Odds ratios (ORs) for IPH as a factor in the pathogenesis of neurologic events were calculated ...
