摘　　要：目的:探讨声学密度定量(AD)技术评价风湿性心脏病患者心肌病变的临床意义。方法:应用AD技术对30例风湿性心脏病患者和30例正常对照组左心室长轴切面、心尖四腔心切面和心尖左室两腔心切面中间段、乳头肌水平左室短轴切面心肌的背向散射值进行测量,按不同节段分别比较病例组和对照组的AII%(平均图像强度百分比)、SDI(标准偏移)及PPI(心动周期变化幅度)值。结果:病例组的AII%值较对照组明显增高(P<0.05),PPI值明显减低(P<0.05),SDI与对照组比较无显著差异(P>0.05)。结论:声学密度定量技术可以用于评价风湿性心脏病患者的心肌病变,协助判断心肌病变程度。Objective：To investigate clinical significance of acoustic densitometry（AD） technology evaluate the changes of myocardium in patients with the rheumatic heart disease.Methods：Use AD technique to measure integral backscatter of parasternal left heart long axis view,parasternal papillary muscle level short axis view,apical 4-chamber view and apical 2-chamber view in 30 patients with the rheumatic heart disease and 30 normal person,compare the AII%,SDI and PPI.Results：The SDI of two groups do not have significant difference;The AII% and PPI of two groups have significant difference.Conclusion：The acoustic densitometry（AD） technology can used to evaluation the changes of myocardium in patients with the rheumatic heart disease.
