Fetal biparietal diameter, transverse thoracic diameter abdominal circumference and area were measured by ultrasound in 50 pregnant women at term not more than 48 hours before delivery. Multiple regressions correlating birth weight with all these parameters were obtained and estimated birth weight (calculated from the regressions) was compared with the actual birth weight. The error in prediction was under 200 g in 56%, under 300 g in 66% and under 400 g in 84% of patients when all fetal measurements were used. It was under 200 g in 48%, under 300 g in 66% and under 400 g in 74% when only the abdominal area was used; and it was under 200 g in 46%, under 300 g in 56% and under 400 g in 82% when the abdominal circumference alone was used. Biparietal diameter and transverse thoracic diameter alone were not useful in predicting birth weight.
在50名足月孕妇分娩前不超过48小时，通过超声测量胎儿双顶径、胸横径、腹围和面积。获得了将出生体重与所有这些参数相关联的多元回归方程，并将根据回归方程计算出的估计出生体重与实际出生体重进行比较。当使用所有胎儿测量值时，56%的患者预测误差在200克以内，66%在300克以内，84%在400克以内。仅使用腹部面积时，48%在200克以内，66%在300克以内，74%在400克以内；仅使用腹围时，46%在200克以内，56%在300克以内，82%在400克以内。仅双顶径和胸横径对预测出生体重没有帮助。
