Abstract

In utero estimates of fetal weight were evaluated prospectively in 109 fetuses with the use of sonographic models developed in a previous study. This report confirms that the best in utero weight estimates result from the use of models based on measurements of head size, abdominal size, and femur length. Since the accuracy of these models (1 SD = 7.5%) is significantly better than those based on measurements of head and body (e.g., biparietal diameter, abdominal circumference), we recommend routine use of such models in obstetric sonography.

摘要

在109例胎儿中，前瞻性地评估了使用先前研究中开发的超声模型进行的宫内胎儿体重估计。本报告证实，基于头围、腹围和股骨长度测量的模型能得出最佳的宫内体重估计值。由于这些模型的准确性（1个标准差 = 7.5%）明显优于基于头和身体测量的模型（例如双顶径、腹围），我们建议在产科超声检查中常规使用此类模型。
