Biparietal diameter at 16 weeks

When you are pregnant, check-ups during pregnancy are a must for every pregnant woman. However, sometimes after the ultrasound report comes out, some expectant mothers will worry that the fetus is too big or too small compared to the top of the head. So, what is the standard of the biparietal diameter at 16 weeks? In order to solve the concerns of many expectant mothers about the baby's development, experts have made the following introduction for everyone.

16 weeks of pregnancy: the average value of biparietal diameter is 3.62±0.58"""" the average value of abdominal circumference is 10.32±1.92"""" the femur length is 2.10±0.51.

17 weeks of pregnancy: the average value of biparietal diameter is 3.97±0.44"""" the average value of abdominal circumference is 11.49±1.62"""" the femur length is 2.52±0.44.

Ultrasound examination of fetal biparietal diameter (from 16th to 40th week)

18 weeks of pregnancy: the average value of biparietal diameter is 4.25±0.53", the average value of abdominal circumference is 12.41±1.89", the average value of femur length is 2.71±0.46.

19 weeks of pregnancy: the average value of biparietal diameter is 4.52±0.53", the average value of abdominal circumference is 13.59±2.30", the average value of femur length is 3.03±0.50.

20 weeks of pregnancy: the average value of biparietal diameter is 4.88±0.58", the average value of abdominal circumference is 14.80±1.89", the femur length is 3.35±0.47.

21 weeks of pregnancy: the average value of biparietal diameter is 5.22±0.42", the average value of abdominal circumference is 15.62±1.84", the average value of femur length is 3.64±0.40.

22 weeks of pregnancy: the average value of biparietal diameter is 5.45±0.57", the average value of abdominal circumference is 16.70±2.23", the average value of femur length is 3.82±0.47.

23 weeks of pregnancy: the average value of biparietal diameter is 5.80±0.44", the average value of abdominal circumference is 17.90±1.85", the femur length is 4.21±0.41.

24 weeks of pregnancy: the average value of biparietal diameter is 6.05±0.50, the average value of abdominal circumference is 18.74±2.23, the average value of femur length is 4.36±0.51.

25 weeks of pregnancy: the average value of biparietal diameter is 6.39±0.70"""" the average value of abdominal circumference is 19.64±2.20"""" the femur length is 4.65±0.42.

26 weeks of pregnancy: the average value of biparietal diameter is 6.68±0.61", the average value of abdominal circumference is 21.62±2.30", the femur length is 4.87±0.41.

27 weeks of pregnancy: the average value of biparietal diameter is 6.98±0.57"""" the average value of abdominal circumference is 21.81±2.12"""" the femur length is 5.10±0.41.

28 weeks of pregnancy: the average value of biparietal diameter is 7.24±0.65"""" the average value of abdominal circumference is 22.86±2.41"""" the femur length is 5.35±0.55.

The following is the relevant content about the standard of biparietal diameter of the fetus by ultrasound examination introduced in detail by experts. I believe that now everyone should have a deep understanding and knowledge of the standard of biparietal diameter at 16 weeks. I hope that the above introduction can help many expectant mothers. Here, experts remind that expectant mothers must do regular pregnancy checkups during pregnancy.
