Detection of intrauterine growth retardation by ultrasound: preliminary communication

In this study, ultrasonic measurements of the fetal head area and abdominal area were obtained in 1200 patients with singleton pregnancies. The results from the 434 who have delivered, indicate that a large proportion of growth-retarded infants cannot be identified by a single late ultrasonic measurement of either area, at 32-34 weeks gestation, as has been previously suggested.
