Determination of biparietal diameter in the second trimester as a predictor of intrauterine growth retardation.
Fetal biparietal diameter (BPD) was measured by ultrasound at 18-21 weeks gestation in 1023 women. The results showed a clear relationship to birth weight at delivery (36 weeks or later): the sensitivity was 24.2%, the predictive value was 18.2%, and the specificity was 92.5%. We propose that BPD measured in the second trimester is a clinically useful predictor of intrauterine growth retardation.
