目的探讨二维超声胎盘测量在预测小胎龄儿（SGA）中的应用价值。方法在妊娠1824周测定胎盘沿胎面最大直径和最大厚度，并在正交平面上重复测定。生物测量滞后被计算为超声胎龄之间的差异，使用胎儿生物测量的每一个估计，和实际胎龄。对这些变量分别进行分析，并将其组合起来作为出生体重的预测因子。
Objectives To determine the utility of two-dimensional (2D) sonographic placental measurements in the prediction of small-for-gestational-age (SGA) infants. Methods The maximal diameter along the fetal surface of the placenta and the maximal placental thickness were measured at 1824 weeks' gestation, and the measurements repeated in the orthogonal plane. Biometric lags were calculated as the difference between sonographic gestational age, estimated using each of a number of fetal biometric measurements, and actual gestational age. These variables were analyzed individually and in combination as predictors of birth weight?
