Deformation imaging by tissue Doppler imaging (TDI) and speckle-tracking echocardiography (STE) are emerging clinical methods. TDI- and STE-derived parameters, such as myocardial strain and strain rate, as well as torsion and twist, provide detailed information about myocardial function and are associated with cardiovascular morbidity and mortality. However, only echocardiographic laboratories with experience in deformation imaging have included these methods in daily clinical practice. In this review, we describe myocardial deformation parameters and relevant echocardiographic methods and address recent developments in the clinical application of deformation imaging.
组织多普勒成像（TDI）和斑点追踪超声心动图（STE）进行的形变成像正成为临床方法。由TDI和STE得出的参数，如心肌应变、应变率以及扭转和捻转，提供了有关心肌功能的详细信息，并与心血管疾病的发病率和死亡率相关。然而，只有在形变成像方面有经验的超声心动图实验室才将这些方法纳入日常临床实践。在本综述中，我们描述了心肌形变参数和相关的超声心动图方法，并探讨了形变成像临床应用的最新进展。
