本文介绍了一种利用多种胎儿生长参数(双顶径、头围、腹围、股骨长度)预测妊娠晚期(28-42wk)月经年龄的新技术。对177例正常妊娠晚期妊娠的评估表明，当两个或多个参数共同使用而不是单个参数单独使用时，预测月经年龄的可变性可以得到显著改善。36wk前的最佳组合是双顶径、腹围和股骨长，36wk后的最佳组合是头围、腹围和股骨长。这些组合的使用导致了较小的平均误差、标准偏差和最大误差。文中给出了回归方程和正常值表格，方便了该测年方法的应用。
A new technique is described for predicting menstrual age in the 3rd trimester of [human] pregnancy (28-42 wk) using multiple fetal growth parameters (biparietal diameter, head circumference, abdominal circumference, femur length). Evaluation of this technique in 177 normal 3rd trimester pregnancies demonstrated that significant improvement in the variability in predicting menstrual age can be achieved when 2 or more parameters are used collectively instead of a single parameter used individually. The optimal combination prior to 36 wk was biparietal diameter, abdominal circumference and femur length, while after 36 wk the optimal combination was head circumference, abdominal circumference and femur length. The use of these combinations resulted in smaller mean errors, SD and maximum errors. Regression equations and tables of normal values are provided to facilitate the use of this dating method.
