Analysis of autopsy data shows that, from the 26th through the 38th gestational weeks, fetal brain weight (BrW) is a function of the 3.124 power of the largest head circumference (HC). Because there is excellent correlation between prenatal ultrasound measurement and postnatal tape measurement of the HC, it is possible to determine fetal BrW in utero. An alteration of the BrW:somatic weight (SW) relationship is an important physical stigma of asymmetric intrauterine growth retardation (IUGR). The value of longitudinal studies of fetal BrW and SW as a means of discriminating between normal and asymmetric growth is tested in a population at risk for IUGR.
尸检数据分析表明，从孕26周到38周，胎儿脑重（BrW）是最大头围（HC）的3.124次幂的函数。由于产前超声测量与产后HC卷尺测量之间存在良好的相关性，因此可以在子宫内确定胎儿的脑重。脑重与体重（SW）关系的改变是不对称性宫内生长受限（IUGR）的一个重要体征。在有IUGR风险的人群中，对胎儿脑重和体重进行纵向研究作为区分正常生长和不对称生长手段的价值进行了测试。
