摘　　要：目的应用三维超声体积自动测量(VOCAL)技术检测胎儿胃泡的发育,建立不同孕周胎儿最大、最小胃泡容积正常范围参考值,并评价其与孕周的关系。方法对筛选出的16～38周正常胎儿共345胎,应用经腹三维超声VO-CAL技术估测胎儿最大、最小胃泡容积,并分析其与孕周的关系。结果应用VOCAL技术可近似测量胎儿最大、最小胃泡容积。正常胎儿最大、最小胃泡容积与孕周呈曲线相关(R2max=0.98、0.96,P均<0.001)。结论三维超声VOCAL技术测量胎儿胃容积有助于评价胎儿胃泡的发育。Objective To evaluate the development of gastric babbles with 3D ultrasound virtual organ computer-aided analysis（VOCAL） technique,and to establish reference ranges for the maximum and minimum gastric volume for normal live fetuses.Methods A total of 345 normal fetuses at 16—38 gestation weeks were recruited.Three-dimensional transabdominal VOCAL technique was used to approximately measure the maximum and minimum gastric volume of the fetus,and to analyze their relationship with gestational age.Results The maximum and minimum gastric volume were obtained in 345 fetuses.The maximum and minimum gastric volume of normal fetuses were curvilinearly associated with gestational age（R2max=0.98,0.96,all P〈0.001）.Conclusion Measurement of fetus gastric volume with VOCAL is helpful to the evaluation on gastric development.
