Fetal biparietal diameter (BPD) and head, chest and abdominal circumferences (HC, CC, AC) were measured by means of real-time B-scan echography. The study population consisted of 198 patients who were hospitalized at Tohoku University Hospital. All live-born infants were delivered within 48 hr after ultrasonic examination. This study was intended to establish criteria for diagnosis of fetuses weighing more than 2,500 g by means of a single ultrasonic measurement of several different fetal growth parameters. When estimated diameter of BPD exceeded 9.0 cm, 96.1% of the infants weighed more than 2,500 g. In all cases in which HC, CC, and AC exceeded 30 cm, the infants weighed more than 2,500 g. Finally, a multiple regression equation was constructed for estimation of birth weight by the values of fetal BPD, HC, CC and AC. The prediction error between prospective birth weight given by this formula and actual birth weight was +/- 200 g. The present method for estimation of fetal weight is simple and useful in obstetrical clinic.
采用实时B超扫描测量胎儿双顶径（BPD）以及头围、胸围和腹围（HC、CC、AC）。研究对象为198名在东北大学医院住院的患者。所有活产婴儿均在超声检查后48小时内分娩。本研究旨在通过对几种不同胎儿生长参数进行单次超声测量，建立诊断体重超过2500克胎儿的标准。当估计的双顶径超过9.0厘米时，96.1%的婴儿体重超过2500克。在所有头围、胸围和腹围超过30厘米的病例中，婴儿体重超过2500克。最后，构建了一个多元回归方程，通过胎儿双顶径、头围、胸围和腹围的值来估计出生体重。该公式预测的预期出生体重与实际出生体重之间的预测误差为±200克。目前这种估计胎儿体重的方法在产科诊所简单且实用。
