The present study was undertaken to establish accurate, convenient, simple and rapid ultrasonographic measurements of fetal parameters and their correlation with gestational age and fetal weight. Relationship with gestational age was studied in 60 fetuses from 348 measurements of the biparietal diameter (BPD) and was also correlated with eight other parameters. There is no doubt that the BPD is the most reliable parameter for estimation of gestational age. In 34 infants, 306 measurements of nine fetal parameters taken within four days before delivery were correlated with their birth weights. Abdominal area gave the highest correlation, compared with other parameters or their combinations. Since combined measurements of several parameters gave only a slightly higher multiple correlation (R = 0.89) with fetal weight than the measurement of abdominal area alone (r = 0.85), their use is not justified as a routine procedure.
本研究旨在建立准确、便捷、简单且快速的胎儿参数超声测量方法，以及这些参数与孕周和胎儿体重的相关性。对60例胎儿的双顶径（BPD）进行了348次测量，研究其与孕周的关系，并与其他八个参数进行了相关性分析。毫无疑问，双顶径是估计孕周最可靠的参数。对34例婴儿在分娩前四天内进行了九项胎儿参数的306次测量，并将其与出生体重进行了相关性分析。与其他参数或其组合相比，腹部面积的相关性最高。由于几个参数的联合测量与胎儿体重的复相关系数（R = 0.89）仅比单独测量腹部面积（r = 0.85）略高，因此将其作为常规程序使用并不合理。
