Serial ultrasound measurements of fetal growth were made during uncomplicated pregnancy in 28 time-mated rhesus monkeys. Gestational sac (GS) size, crown-rump length (CRL), biparietal diameter (BPD), head circumference (HC), head area (HA), abdominal circumference (AC), abdominal area (AA), and femur length (FL) were measured. Average longitudinal growth curves for each parameter were obtained from individual fetal growth curves. Data analysis indicated that the linear model was optimal for GS, CRL, HA, AA, and FL. The linear-quadratic model was optimal for AC, and the linear-cubic model was optimal for BPD and HC.

“…In some investigations the ratio fetal head/abdomen has been used to detect intra-uterine growth retardation (22,23,24,25,26,27). In some of these studies the prevalence of intra-uterine growth retardation has been high (23, 28,27) or not described (24,26). Comparative studies have shown abdominal measurements alone to be more useful than the ratio fetal head/abdomen, which is not surprising since symmetric growth retardation occurs in more than 80% of retarded growth in some studies (21).…”

Based upon 2194 consecutive pregnancies with known gestational age, formulas for weight deviation predicted in the 32nd and 37th gestational week were estimated by multiple linear regression on the measurements of the abdominal diameter (AD) and the biparietal diameter (BPD) of the first 64% of the pregnancies. The usefulness of the screening was evaluated on the remaining 36%. An attempt to diagnose light for gestational age (LGA) infants resulted in either a low sensitivity or a low predictive value of a positive test. The late third trimester screening was more sensitive than the early, indicating LGA as a late phenomenon in pregnancy. Knowing the result from the late scanning, the result from the early scanning contributed almost no further information about whether the infant would be LGA at birth. Basic epidemiological characteristics of other comparable investigations on high-risk pregnancies and non selected pregnancies are presented.

“…A placental size below the 10th centile was seen with birthweights up to the 84th centile. Varma et al (1979) studied the predictive efficacy of AA measurements in 186 high-risk pregnancies where the prevalence of birthweight <loth centile was 1970. The sensitivity at 33 weeks gestation was 80% and very similar at 10 days before delivery.…”

Summary. . The value of fetal biparietal diameter and abdominal area, total intrauterine, intra‐amniotic and placental volume measurements for predicting small‐for‐dates babies in a high‐risk obstetric population was investigated in 130 women. A parallel planimetric area method was used to measure volume. The commonest risk factors were suspected intrauterine growth‐retardation, hypertensive complications and previous poor obstetric history. The prevalence of birthweight at and below the 10th or 3rd centiles was 30 and 16% respectively. Fetal abdominal area and total intrauterine volume measurements had the highest and comparable sensitivity, specificity and positive predictive value in the detection of infants with birthweights of 10th and 3rd centiles. While these measurements are of use in consolidating the clinical diagnosis of small‐for‐dates fetuses (growth retardation), high false positive rates (10% and 16–17% for birthweights 10th centile, and 3rd centile respectively) make further discriminatory tests necessary for part of the population.
