Abstract:
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.
