Some clinicians use the unweighted mean of the 4 most commonly used biometric parameters ( biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) ) to establish a gestational age [22] Establish a fetal ultrasound database to dynamically observe fetal growth curves. In order to calculate fetal length, you will need only the FL measurement, which represents the length of the femur.

Answered by : Dr. Dattaprasad ( Infertility Specialist) Suggest treatment for BPD . 33, 34 The limiting factors in this formula are the inclusion only of BPD and AC rather than HC, AC, and possibly FL, and the utilization of the same formula for all fetuses, regardless of gestational age and growth status. FL in mm : Gestational Age = weeks . This ratio helps to differentiate between symmetric IUGR, asymmetric IUGR and a normally proportioned fetus. 2 – 4 The calculated EFWs were then adjusted for interval growth between the dates of sonography and delivery using published sonographic fetal growth velocity standards. HC - Head Circumference The accuracy of gestational age calculated from HC is sligtly better than that derived from BPD. BPD and OFD were measured from the outer borders of the skull and head circumference (HC) was calculated [3.14 x(BPD+OFD)/2].
