Hemodynamic Research Development of Carotid Atherosclerosis Based on MR Imaging

Abstract

Abstract:

Atheroslerotic lesions tend to be localized at the area with sophisticated flow status regardless of the underlying risk factors involved, which suggested that hemodynamic factors play an important and predominant role in formation and development of atherosclerosis. Based on magnetic resonance images, combined with post-processing techniques, hemodynamic status can be assessed. Previous studies have analyzed hemodynamics features in normal and stenosed carotids. The association between hemodynamics factors and plaque vulnerability has been proven. Arterial hemodynamics parameters including wall shear stress, pressure are important factors in formation and development of atherosclerotic plaques.

摘要：

动脉粥样硬化斑块常发生于血流动力学状态复杂的区域，显示局部血流的流体力学特性在动脉粥样硬化病变发生发展中起到重要作用。基于磁共振成像结合图像后处理技术，可对动脉血流动力学状态进行评估。既往研究已经对正常和狭窄颈动脉的血流动力学特征进行了分析；而血流动力学因素与斑块易损性之间的相关性也已经得到证实。包括管壁应力、压力等动脉血流动力学参数的综合作用是斑块发生发展变化中的重要因素。
