title: Intrauterine growth retardation: ultrasonic diagnosis.
abstract: In 3258 pregnant mothers with ascertained gestational length, 3736 biparietal and transverse thoracic diameters were measured by a rapid screen ultrasound device. The data were processed by computer and the possibilities of detection and typing of intrauterine fetal retardation were examined. Serial measurements performed during pregnancy satisfactorily detected type I or the proportional type. The asymmetrical form, type II, can be distinguished by the Neyman-Pearson method. The decision curves applicable for each gestational week have been computed and are described. They can also be used for determination of the degree of intrauterine wasting.
