Well, he has worked in a big nationally recognized "best women's hospital" for 3 decades, so I kinda cannot question his experience. According to the results, fetuses in the breech position have a significantly lower BPD compared to HC or FL, and HC and FL parameters correlate with gestational age. AC together with biparietal diameter, head circumference, and femur length are computed to produce an estimate of fetal weight. In this longitudinal study we sought to investigate the presence of different abnormal fetal growth patterns in the pregnant diabetic. Pre-determined and LZR biparietal head size.
