Hemodynamic Imaging Techniques and New Advances in Carotid Artery Plaques
Carotid atherosclerotic stenosis is one of the main diseases causing ischemic stroke(IS),and early detection of stenosis and identification of vulnerable plaques can significantly improve the efficacy and reduce the mortality and disability rates.Hemodynamic changes are closely related to the formation,development,and rupture of plaques.The use of hemodynamic parameters to assess the risk of atherosclerotic plaque rupture and guide the selection of clinical treatment methods has become the focus of research on the precise diagnosis and treatment of atherosclerosis.However,the mechanism of the interaction between hemodynamic parameters and plaques has not been fully elucidated,and hemodynamic imaging techniques have not been widely developed.This article reviews the previous literature to further sort out the imaging progress of carotid plaque hemodynamics,as well as the interaction mechanism between hemodynamic changes and plaque formation,development and rupture,and discuss the relationship between these features and IS,aiming to evaluate the predictive value of plaque composition and hemodynamics in stroke events caused by carotid atherosclerotic stenosis.
