[The use of Rossavik's mathematical model in determining individual intrauterine growth curves. Our experience].

Objective: To evaluate the performance of Rossavik growth models, derived from II trimester ultrasound measurements, to predict growth in normally growing fetuses.

Design: Comparison between observed measurements after 25 weeks and those predicted by Rossavik growth models determined from the data collected in 2 ultrasound examinations at approximately 16 weeks and 24 weeks.

Setting: Teaching hospital obstetric unit, in Florence.
