When it comes to biparietal diameter, I believe many women are familiar with it. Especially women who have been pregnant are aware of the significance of biparietal diameter. In fact, the fetal biparietal diameter can be used to calculate their weight. So, what is the formula for calculating fetal weight using biparietal diameter?
Generally, doctors will judge the development of the fetus based on the development of its biparietal diameter, and even determine whether a woman can give birth naturally. So regular prenatal check ups are necessary during pregnancy, and the results cannot be ignored. If the fetal biparietal diameter is greater than 8.5 in B-ultrasound, it indicates that the embryo has matured.
If a woman wants to calculate fetal weight, the formula for fetal weight is 900 times the fetal biparietal diameter minus 5200. The calculated fetal weight in this way may differ significantly from the actual fetal weight, so women should not blindly trust this calculated weight. In addition, parents can also use fetal head circumference, abdominal circumference, femur length, etc. to calculate fetal weight, so that the calculated weight will be more accurate.
During pregnancy, in addition to knowing the fetal biparietal diameter, women also need to understand the growth of other parts of the fetus, such as their head circumference, abdominal circumference, etc. Generally, as the fetus continues to grow, their biparietal diameter, abdominal circumference, etc. will also change constantly. Therefore, every time a woman goes to the hospital for a pregnancy check-up, she needs to compare these data to determine the growth and development of the fetus.
