Abstract

The reliability of sonar biparietal diameter measurements and the assessment of the sources of potential error are of great importance in the estimation of gestational age and in the diagnosis of fetal growth retardation. The following study was undertaken to ascertain the reproducibility of several successive steps in the measurement of the biparietal diameter and to compare intrauterine sonar measurements with direct caliper measurements after abortion of delivery. Tables were developed from these data from which it can be ascertained if a growth rate found during a specific period in gestation is above or below the mean or below the tenth, fifth or first percentile.
