摘　　要：目的探讨DFY-Ⅱ型超声图像定量分析在评估不同孕周胎儿肺/肝回声比值中的价值。方法收集孕24~41周健康孕妇315名,获取胎儿右侧旁矢状切面图像,采用DFY-Ⅱ型超声图像定量分析仪分析胎儿肺、肝回声强度并计算两者的比值,分析肺/肝回声比值与孕周的相关性。结果胎儿肺/肝回声比值与孕周呈正相关性(r=0.94,P<0.05),直线回归方程为Y=0.60+0.07 X(r^2=0.883)。结论采用DFY-Ⅱ型超声图像定量分析仪分析胎儿肺/肝回声比值可作为评估胎儿肺发育的有效方法。Objective To investigate the application value of DFY-Ⅱ ultrasound imaging analysis software in evaluation of fetal lung maturity in different pregnancy. Methods Totally 315 cases of healthy single pregnancies （24-41 weeks） were collected. The sonographic views of fetal right side sagittal plane were obtained. The echo intensity of fetal lung and liver were analyzed and the ratio was canculated with DFY-Ⅱ ultrasound imaging analysis software. Results The ratio of echo intensity from fetal lung and liver had positive correlation with gestational weeks （r=0.94, P〈0.05）, the linear regression equation was Y=0.60＋0.07X （r2=0.883）. Conclusion The ratio of echo intensity by fetal lung and liver analyzed with DFY-Ⅱ ultrasound imaging analysis software can be an effective method to evaluate fetal lung maturity.
