摘　　要：尽管超声影像学进步较快,但在临床心脏超声工作中,仍较多袭用目测分析室壁节段运动的方法评价左室局部功能。斑点追踪为一种超声影像新技术,能对心肌运动进行定量分析,且较少受人为因素的干扰,在左室局部心肌力学的分析中具有重要作用。本综述就心肌结构及斑点追踪技术原理作一客观评价。Although distinguished progress has been made in ultrasound imaging arena, visual assessment of segmental wall motion, especially in evaluating regional left ventricular function, is still playing its predominant role in clinical echocardiography applications. Speckle tracking imaging, as a new imaging modality with less subjective influences,may be used as a substantial tool in analyzing left ventricular function for its quantitative analysis of myocardial motion. The myocardial structure and the principle of speckle tracking technology are reviewed in this article.
