摘　　要：目的比较二维斑点追踪成像(2D-STI)与三维斑点追踪成像(3D-STI)检测川崎病患儿左室收缩功能的临床价值。方法应用3D-STI和2D-STI技术分别检测50例川崎病患儿左室心肌不同部位(基底部、中间段、心尖部)节段心肌及整体的相关参数,并对两种技术检测结果进行比较分析。结果 2D-STI与3D-STI所测左室收缩末期和舒张末期容积(EDV、ESV)比较差异均有统计学意义(均P<0.05);2D-STI与3D-STI所测基底部收缩期纵向、圆周、径向峰值应变(LS、CS、RS),中间段LS,心尖部LS、CS、RS比较差异均有统计学意义(均P<0.05);中间段CS、RS及左右冠状动脉扩张情况比较差异均无统计学意义。结论 2D-STI和3D-STI对川崎病患儿冠状动脉扩张的检查并无差异;但相比2D-ST,3D-STI在心肌基底部、中间段、心尖部所测峰值应变不会随心脏运动而显著改变,检测结果能更好地反映患儿左室心脏功能。Objective To compare the clinical value of two-dimensional and three-dimensional speckle tracking(2D-STI,3D-STI)in dectecting left ventricular systolic function in children with Kawasaki Disease.Methods 2D-STI and 3D-STI techniques were used to detect different position of the left ventricular myocardium(basal,middle,and apical)and myocardial and global parameters in 50 children with Kawasaki disease in our hospital,and the results of the two technologies were compared.Results The difference of EDV and ESV were statistically significant between 2D-STI and 3D-STI(both P<0.05).The differences of LS,CS,RS in basal segment,LS in the middle segment,and LS,CS,RS in apical segment were statistically significant between 2D-STI and 3D-STI(all P<0.05).There was no statistically significant difference of CS,RS in the middle segment and left and right coronary artery expansion between 2D-STI and 3D-STI.Conclusion 2D-STI and 3D-STI could not differ in the examination of coronary artery dilation in children with Kawasaki disease.But compared with 2D-STI,the strain peak measured at the basal,middle,and apical segment of the myocardium by 3D-STI could not change with the heart movement,which can better reflect the left ventricular function of the children’s heart.
