Bpd, hc, ac, fl normal range: 2

2. What measurements are taken during a fetal biometry scan? During a fetal biometry scan, the technician typically measures the biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) to evaluate the baby’s growth and development. 3. Why is fetal biometry important? What is BPD HC AC FL in fetal biometry? Ultrasound measurements of biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) are used to evaluate fetal growth and estimate fetal weight. What does biometry mean in pregnancy? Fetal biometry means the measurement of the anatomic segments of the fetus by ultrasound. The following measurements are the most common: CRL, BPD, head circumference (HC), AC, and femur length (FL) [14]. What is normal bpd in ... The normal range for BPD in pregnancy 29.4mm at 14 weeks, 49.4mm at 20 weeks, 78.4mm at 30 weeks, 91.5 at 37 weeks and 95.6mm at 40 weeks. If the BPD in pregnancy measurement is outside this range, it may indicate a problem with foetal growth or development problem. FL/AC (FEMUR LENGTH TO ABDOMINAL CIRCUMFERENCE RATIO) (3) Normal = 22 ± 2% (constant after 24 weeks). When ratio falls <20% or >24%, the AC should not be used in the assessment of gestational age. Growth retardation = >24%. Macrosomia = <20% (3).
