The accuracy of gestational age prediction in 30 growth-retarded fetuses as derived from the fetal femur length (FL) was compared with that derived from the biparietal diameter (BPD). The mean difference between the actual and predicted gestational age was smaller when FL was used, but the difference did not reach statistical significance when compared with that associated with the use of the BPD. No consistent pattern of head/limb growth retardation was obvious. The femur length and BPD were both reduced in varying proportions in the growth-retarded fetuses. The significance of such findings in the assessment of intrauterine growth retardation is discussed.
对30例生长受限胎儿，比较了根据胎儿股骨长度（FL）和双顶径（BPD）预测胎龄的准确性。使用FL时，实际胎龄与预测胎龄的平均差异较小，但与使用BPD时相比，该差异未达到统计学显著性。未发现明显一致的头/肢生长受限模式。生长受限胎儿的股骨长度和双顶径均有不同程度的减小。讨论了这些发现对评估宫内生长受限的意义。
