摘　　要：心肌机械离散为应变的衍生参数,可更细微地反映心肌微观结构和电生理的改变,有助于对心肌疾病引起的心律失常等主要不良心血管事件的风险分层。心脏磁共振(CMR)具有更高的空间分辨力和软组织分辨力,测量的机械离散更准确,但目前基于CMR组织特征追踪(CMR-FT)技术获得机械离散的研究很少。就基于CMR-FT的心肌机械离散的概念和评价方法及其在缺血和非缺血性心肌病中的应用研究进展予以综述。Myocardial mechanical dispersion is a derived parameter of strain and can be used to subtly identify the changes in myocardial microstructure and electrophysiology.It is useful for stratifying the risk of major adverse cardiovascular events,such as arrhythmias caused by myocardial diseases.Cardiac magnetic resonance(CMR)has high spatial and soft tissue resolution,and mechanical dispersion measurements are more accurately.However,there are few studies on mechanical dispersion based on CMR-feature tracking(CMR-FT)technology.This article reviews the conception and assessment methods of myocardial mechanical dispersion based on CMR-FT and its application in ischemic and nonischemic cardiomyopathy.
