Hello doctor I am 30 weeks 6 days late pregnancy today to do ultrasound biparietal diameter 8.5 is not too big ah?I'm afraid that the fetus will have mental problems.
Condition Analysis:
Hello!The ultrasound results indicate that the fetal biparietal diameter is relatively large, the amniotic fluid is moderate, the femoral length is generally normal, the abdominal circumference and head circumference are also generally normal and a little larger, this situation does not need to be too nervous, there must be errors in the ultrasound examination, and you can verify the pregnancy week again, it is recommended that you relax, eat normally and do regular maternity checks.
Condition Analysis:
The fetal head may be large due to the excessive nutritional intake during pregnancy and other factors, and there is no need to worry if there is no problem in the screening of obstetric diseases.
Condition Analysis:
If you look at the head circumference, it is still possible, the double parietal diameter is really large, may also be related to the genetic level, you can go to the prenatal clinic to see, in addition to a fetal cranial MRI test, to exclude other brain cranial system diseases.
Condition Analysis:
The normal value of biparietal diameter at 30 weeks is 75mm, femur length is usually 57mm, head circumference is 275mm and abdominal circumference is 258mm.However, the growth and development of the fetus may vary, so as long as the number of weeks of menopause and the size of the fetus in the ultrasound examination, the difference of about one week between the top and bottom is normal, and whether the brain development is normal or not can not be judged according to the size.
