What is BPD in pregnancy ultrasound?

Is the BPD-fl pregnancy chart confusing?
Understanding these numbers and chart readings is confusing. However, your ultrasound technician and OBGYN will explain your fetus’ growth and development corresponding to the BPD-FL pregnancy chart. If there are any concerns, you will get to know about them.

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.
What is fl chart in pregnancy?
Much like BPD, HC, AC, FL chart measures the length of the thigh bone to ensure the standard and healthy development of the baby. The FL is calculated using digital tools during the ultrasound imaging.
