超声图像定量分析在胎儿肺发育评估中的应用

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+0.07X(r2=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.
