在对361名[人类]胎儿进行的横断面研究中，开发了基于4项胎儿参数（双顶径、头围、腹围和股骨长度）单独和组合使用的实时超声测量来预测月经年龄的回归模型。月经周14至42周。头围和股骨长度是年龄最强的个体预测因子。一些胎儿参数的组合，包括头围和股骨长度的组合，提供了年龄估计，这是显着优于（P = 0.05），比那些单独使用任何单一的参数。研究还表明，在特定情况下，简单地对个人年龄估计数取平均值，所得到的结果与在复杂回归方程中使用相同参数所得到的结果没有显著差异。这个系统的优点和潜在的陷阱的胎儿约会进行了讨论。
Regression models for predicting menstrual age based on real-time sonographic measurements of 4 fetal parameters (biparietal diameter, head circumference, abdominal circumference and femur length), used alone and in combination, were developed in a cross-sectional study of 361 [human] fetuses between 14 and 42 menstrual wk. The head circumference and femur length were the strongest individuual predictors of age. A number of combinations of fetal parameters, including the combination of head circumference and femur length, provided age estimates that were significantly better (P = 0.05) than those using any single parameter alone. It was also demonstrated that simply averaging individual age estimates in a given case could provide results that were not significantly different from those obtained by using the same parameters in a complex regression equation. The advantages and potential pitfalls of this system of fetal dating are discussed.
