The purpose of this study was to compare ultrasonic measurements of fetal abdominal circumference to ultrasonic measurements of fetal biparietal diameter, as a means of estimating fetal body weight. Of 58 fetuses who had abdominal circumferences measured, 48 (82%) of the predicted weights were within 15% of the actual birth weights. Forty-four of the same 58 fetuses had satisfactory biparietal diameter measurements, but only 21 (48%) of the predicted weights were within 15% of the actual birthweights. Ultrasonic measurement of abdominal circumference appears to be a more reliable index of fetal body weight than other currently available techniques.
本研究的目的是比较胎儿腹围的超声测量值与胎儿双顶径的超声测量值，以此作为估计胎儿体重的一种方法。在58例测量了腹围的胎儿中，48例（82%）预测体重与实际出生体重相差在15%以内。同58例胎儿中有44例双顶径测量结果令人满意，但只有21例（48%）预测体重与实际出生体重相差在15%以内。与目前其他可用技术相比，超声测量腹围似乎是更可靠的胎儿体重指标。
