Intra-Uterine Fetal Growth Studied by Ultrasonic Biparietal Measurements: The Percentiles of Biparietal Distribution

Abstract

Fetal biparietal diameter was measured in utero with ultrasonic techniques, in 1 Oil patients with 3 032 measurements at gestational ages ranging from 15 to 43 weeks. The distribution of these values, the mean weekly increments, together with the 5th to 95th percentiles are presented in tabular and graphic forms. The mean values correspond to those quoted in other investigations.
