Normal range curves for the growth of fetal biparietal diameter (BPD), occipitofrontal diameter (OFD), mean abdominal diameter (AD), and femur length (FL) were obtained in a longitudinal series of ultrasound measurements in 19 normal pregnancies. Regression analysis was used to fit the data to equations. The best equations for BPD and AD on gestational are close to similar longitudinally obtained regression curves from other Scandinavian countries.
