Tissue Doppler Imaging (TDI) is a recent ultrasound technique that enables the quantification of regional myocardial function by measuring myocardial velocities. Three TDI modes are available: pulsed wave mode, 2D color mode and color M-mode. Each of them allows the specific analysis of radial and longitudinal myocardial motion. Both phase and amplitude of regional myocardial motion may be analyzed by TDI. Therefore, TDI appears to be a precise non-invasive method for assessing myocardial dysfunction: several studies have already shown that TDI is a more sensitive technique than conventional echocardiography for detecting mild myocardial alterations in human heart diseases as well as in animal models.
组织多普勒成像（TDI）是一种最新的超声技术，它能够通过测量心肌速度来定量分析局部心肌功能。有三种TDI模式可供使用：脉冲波模式、二维彩色模式和彩色M型模式。每种模式都能对心肌的径向和纵向运动进行特定分析。TDI可以分析局部心肌运动的相位和幅度。因此，TDI似乎是一种评估心肌功能障碍的精确无创方法：多项研究已经表明，在检测人类心脏病以及动物模型中的轻度心肌改变方面，TDI是一种比传统超声心动图更敏感的技术。
