Some malformations can be compared. Clearly visible, but some may require follow-up testing. The third ultrasound examination★ Time: Around 16 weeks. This time it mainly measures the size of the baby (biparietal diameter, femur length, etc.), as well as the basic placenta, amniotic fluid, fetal heart rate, and whether there are any structural deformities. In addition, you need to confirm whether there is a head halo. If some abnormal babies do not have a head halo, the baby will not be very good.
