The prenatal determination of fetal weight by dynamic scanning

An equation based on ultrasound measurements to estimate fetal weight must reflect the relationships between parameters of fetal size and growth as well as the change in fetal shape which occurs in relation to varying nutritional supplies. Four equations have been compared with respect to these demands. The material was collected from everyday practice in our hospital. Good results were obtained using two of the equations, and it was suggested that they may serve as valuable tools in studies of fetal growth.
