Under normal circumstances, fetal cleft lip and palate can be screened for deformity by ultrasound. But the accuracy of inspection is not 100%. It may also be invisible because the fetal face is not clearly displayed. Four-dimensional color Doppler ultrasound belongs to a method and means of fetal system malformation screening. Although the clarity and accuracy of four-dimensional color Doppler ultrasound examination are obviously improved compared with ordinary color Doppler ultrasound and B-ultrasound, it still has great limitations, that is to say, four-dimensional color Doppler ultrasound is not omnipotent, and the detection rate for many small deformities is relatively low.
As long as you can see your face clearly. Sometimes I can't see my face clearly because of the fetal position, so I can't see it. But you can ask the doctor, let the doctor see it clearly for you, leave if you can't see it clearly, and wait until the fetal posture changes! We can distinguish two-dimensional ultrasound, three-dimensional ultrasound and thinking ultrasound. First of all, two-dimensional ultrasound is what we understand as B-ultrasound, which shows the cross-sectional image of the event. For example, you can only see the cross section of watermelon on the screen. You can meet a responsible doctor. I spent hundreds of fucking dollars doing four-dimensional with Bauer in our local hospital (Jiajia Hospital), and the inspection report was as short as the B-ultrasound report of tens of dollars! Not careful at all! I feel that the doctor is very impatient.
Generally speaking, you can, but you can't trust four-dimensional color Doppler ultrasound. Because some expectant mothers say that the fetus has such and such problems after four dimensions, but there is no problem when it is born, so four dimensions is just a kind of participation.
