My boy's head isn't small at all, but why his belly so much smaller! The long axis of the diaphysis of the femur is most accurately measured when the ultrasound beam of insonation is perpendicular to the shaft. The measurements that are used in equations to estimate weight usually include biparietal (head) diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur (thigh bone) length (FL). The abdomen should not be compressed during image acquisition. Cesarean section on request at 39 weeks: impact on shoulder dystocia, fetal trauma, neonatal encephalopathy, and intrauterine fetal demise. FOIA Lots can change in the next 20 or so weeks. Well its the same in utero. Microcephaly is diagnosed when the head circumference falls below 2 or 3 or even more standard deviations of the norm. The fetuses with trisomy 21 had significantly shorter mean femur lengths, narrower occipitofrontal diameters, and increased biparietal diameter (BPD)/femur length and abdominal circumference/femur length ratios. Biparietal diameter/femur length ratio, cephalic index, and femur length measurements: not reliable screening techniques for Down syndrome. Now at 32 wks her measurements are at the 52nd percentile, and her belly is a week ahead. HC/AC (Ratio of The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS).
