## Abstract A group of 252 patients who had total intrauterine volume (TIUV) measurements after 20 weeks menstrual age were evaluated for prediction of growth retardation. The measurements were compared to previously published normal values derived at our institution. The birth weights of these pat

Abstract
Recent literature has suggested that total intrauterine volume (TIUV) estimation is useful for distinguishing normal from growth‐retarded fetuses. One hundred seventy‐nine measurements of TIUV were obtained from the ultrasonograms taken between 21 and 40 weeks of gestation in 140 patients who delivered average birthweight babies. We constructed a mean curve for TIUV with upper and lower 2.5 and 10% tolerance limits and later evaluated the TIUV's of 16 patients with growth‐retarded fetuses. Nine of these fetuses had birthweights below the fifth percentile for gestational age, and in each of these pregnancies the TIUV ultimately fell below the lower 2.5% tolerance limit.

We evaluated the predictiveness of sonographically estimated fetal weight as a function of the estimation of probability of having intrauterine growth retardation (IUGR) before obtaining an ultrasound scan (prior probability). The value of the estimated fetal weight resided more in its high specific
## Abstract Four hundred and five women with singleton pregnancies and fetal age determination by crown‐rump length were classified on the basis of their prenatal clinical findings into four risk categories for intrauterine growth retardation (IUGR), defined as a neonatal weight below the 10th perc
