Ultrasound foretells stroke risk based on carotid plaque morphology

November 4, 2008 Diagnostic Imaging. Ultrasound foretells stroke risk based on carotid plaque morphology By H.A. Abella Results from a large study by Italian investigators suggest that ultrasound can predict the risk of stroke in mostly asymptomatic patients based on the assessment of carotid artery plaque morphology, not just stenosis degree. Sonographic surveillance of plaque evolution could boost stroke prevention. Researchers have previously defined the role of vascular risk factors, such as hypertension and diabetes, in the development of atherosclerosis. The factors that determine the vulnerability of plaque, however, remain controversial.
