摘　　要：胸部放疗会引起心脏损伤,而超声心动图是检测胸部放疗致心脏损害最常用的方法。Tei指数、实时三维超声心动图以及瞬时波强技术可以从整体上评价心脏功能,但在精确区分收缩和舒张功能受损方面受到一定限制;组织多普勒成像技术、超声背向散射积分、应变、应变率成像技术和二维斑点追踪显像技术作为能够较准确反映局部心脏功能状态的技术,在反映心脏整体功能方面受到一些因素的影响。Thoracic radiotherapy can cause cardiac injury,and echocardiography is the most common method to detect it.Here is to describe several new techniques of echocardiography in the evaluation of cardiac injury in the application and in prospect.Tei index,real-time three-dimensional echocardiography,wave intensity can evaluate the overall cardiac function,but have certain restrictions in the precise distinction of systolic and diastolic dysfunction.Technologies such as Doppler tissue imaging,integrated backscatter,strain rate imaging,speckle-tracking imaging can more accurately reflect the regional cardiac function,but are influenced by a number of factors when reflecting overall cardiac function.
