How is Biparietal diameter measured?
The BPD should be measured on an axial plane that traverses the thalami, and cavum septum pellucidum. The transducer must be perpendicular to the central axis of the head, and thus the hemispheres and calvaria should appear symmetric. The calipers should be placed at the: outer edge of the near calvarial wall.

What is BPD HC AC and FL in pregnancy?
Biparietal diameter (BPD) is one of the basic biometric parameters used to assess fetal size. BPD together with head circumference (HC), abdominal circumference (AC), and femur length (FL) are computed to produce an estimate of fetal weight.
What is the normal BPD at 37 weeks?
Results: The mean biparietal diameter value was 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. There was a positive relationship between gestational age and biparietal diameter with correlation coefficient of R2 = 0.9996 (P < 0.001), and with fetal weight.
How is the biparietal diameter of a fetus measured?
Biparietal diameter (BPD) is one of the basic biometric parameters used to assess fetal size. BPD together with head circumference (HC), abdominal circumference (AC), and femur length (FL) are computed to produce an estimate of fetal weight.
Who is the doctor that takes the biparietal diameter?
Krissi Danielsson, MD is a doctor of family medicine and an advocate for those who have experienced miscarriage. Meredith Shur, MD, FACOG, is board-certified in obstetrics and gynecology, as well as a certified medical examiner. Biparietal diameter (BPD) is one of many measurements that are taken during pregnancy ultrasound procedures.
How is the diameter of the parietal bone measured?
It is a measurement of the diameter across your developing baby’s skull, from one parietal bone to the other. The BPD is used to estimate fetal weight and gestational age. The other measurements that are used to calculate fetal weight include abdominal circumference and femur length. 1 What Are the Parietal Bones?
How to calculate the percentile of the femur?
Calculations are based on the 4 common fetal measurements, biparietal diameter (BPD), head circumference (HC), femur length (FL), and abdominal circumference (AC). Many studies have devised different formulas.
