Is obstetric examination four-dimensional ultrasound more advanced?

Four-dimensional color Doppler ultrasound is much more advanced than general B-mode ultrasound, which is because it will see the fetus more three-dimensionally, especially some fetal surface abnormalities, that is, his face has cleft lip or cleft palate. Some of these cases, there are fetal heart abnormalities. For example, congenital tetralogy of Falos and ventricular septal defect, etc., can be seen clearly through four-dimensional color Doppler ultrasound, these general B-ultrasound words are not visible, so to 22 to 24 weeks of pregnancy, to do a four-dimensional color Doppler ultrasound, to see the fetal development, so that you can rule out whether the fetus has malformations.
