摘　　要：超声心动图是无创评估儿童心血管系统的主要手段。然而,常规超声心动图因时间分辨率较低无法观察和分析短暂的心脏运动事件和瞬时时相,也无法评估心肌机械力学特性。近年来,超声成像技术和计算能力的进步极大地促进了超高速心脏剪切波成像的发展,允许5000帧/s的速度经胸心脏成像,具备实时观测心脏组织的快速动态运动,获取心肌属性、功能以及心脏血流模式优势,能更好地诊断儿童心血管疾病。本文就超高速心脏剪切波成像技术原理及目前在儿科心脏成像方面的最新应用研究进展进行综述。Echocardiography is the primary method for noninvasive evaluation of cardiovascular system in children.However,conventional echocardiography cannot observe and analyze transient cardiac events and transient phases due to its low temporal resolution,nor can it evaluate the mechanical properties of myocardium.In recent years,ultrasonic imaging technology,and the improvement of computing capacity greatly promoted the development of the ultrafast cardiac shear wave imaging,allowing the speed of 5000 frames/s via chest cardiac imaging,has fast dynamic movement of heart tissue,real-time observation for myocardial properties,function and blood flow to the heart pattern advantages,can better diagnose cardiovascular disease in children.In this paper,the principle of ultrafast cardiac shear wave imaging and its recent application in pediatric cardiac imaging are reviewed.
