In this article, the authors discuss different semi-quantitative methods for the analysis of global and regional myocardial function. Analysis of endocardial motion and direct measurements of myocardial velocities are the basic principles. The former is a two-dimensional technique which, however, requires good image quality and which is influenced by motion artefacts. The latter technique has a better signal to noise ratio and offers the opportunity to sufficiently quantify diastole. Strain rate imaging is a new and interesting way to display and evaluate regional myocardial deformation.
在本文中，作者讨论了用于分析整体和局部心肌功能的不同半定量方法。心内膜运动分析和心肌速度的直接测量是其基本原理。前者是一种二维技术，然而，它需要良好的图像质量并且会受到运动伪影的影响。后一种技术具有更好的信噪比，并且提供了充分量化舒张期的机会。应变率成像为显示和评估局部心肌变形提供了一种新颖且有趣的方法。
