Patient's question:
Pregnancy at 35 weeks 3, 4D ultrasound results:Biparietal diameter (BPD) 8.9 cm, Head circumference (HC) 31.4 cm, Abdominal circumference (AC) 32.5 cm, Femur length 6.8 cm, Humerus length 6.2 cm, Cerebellar transverse diameter 4.5 cm, Cisterna magna width 0.6 cm, Interorbital distance 1.4 cm, Amniotic fluid 5.7 cm, 3.9 cm, 5.6 cm, 2.9 cm, Left renal collecting system 0.37 cm, Right renal collecting system 0.21 cm.
Is the head circumference and abdominal circumference larger than normal? Is the amniotic fluid volume excessive?
Doctor's answer:
Hello, the fetal biparietal diameter is 82 mm, equivalent to 33 weeks of pregnancy, the head circumference is 282 mm, equivalent to 31 weeks of pregnancy, the abdominal circumference is 294 mm, equivalent to 33 weeks of pregnancy, and the femur length is 55 mm, equivalent to 29 weeks of pregnancy.According to the ultrasound results, the fetus is developing normally and is consistent with the actual gestational age. The biparietal diameter and abdominal circumference are slightly larger, indicating that the fetus is slightly overweight, which is normal. Keeping a relaxed mood and attending prenatal check-ups on time is sufficient.
It is recommended to eat more nutritious foods during pregnancy, engage in appropriate exercise, and get plenty of rest.
