   1. What is the biparietal diameter of an average baby at birth

   The biparietal diameter of a full-term pregnancy is generally between About 9.3cm. Biparietal diameter refers to the length of the widest parts on the left and right sides of the fetal head, also known as the \”large transverse diameter of the head.\” Ultrasound examination to measure the biparietal diameter can be used as a basis to observe whether the child\’s development is normal, determine whether there is cephalopelvic disproportion, and whether the child can be delivered normally and smoothly. At the same time, fetal weight can also be roughly estimated by combining biparietal diameter, femoral head, abdominal circumference, head circumference, subcutaneous fat layer thickness, etc.

   2. B-ultrasound shows which part of the fetus the biparietal diameter refers to

   The biparietal diameter of the fetal head refers to the length of the widest parts on the left and right sides of the fetal head, also known as the \”large transverse diameter of the fetal head\”. Also known as bpd, it can be used to observe the development of children, determine whether there is cephalopelvic imbalance, and whether the delivery is smooth. It should reach 9.3 cm or more during term time. The baby\’s weight can be calculated based on the biparietal diameter. Double the top diameter 900 minus 5200. This is the baby\’s weight.
