Is 4D accurate?

Pregnant women are generally recommended to do four-dimensional color Doppler examination. Four-dimensional color Doppler examination is usually said to be a large row of abnormal examination, mainly used to check the development of various organs of the baby. You can choose to do it in about 22-26 weeks of pregnancy, because the size of the fetus and amniotic fluid, bone echo influence is relatively small, do four-dimensional color Doppler results will be more accurate, you can clearly see whether the baby has abnormalities. However, due to fetal position, amniotic fluid and maternal factors, or the limitations of ultrasound technology, it is not possible to detect all fetal abnormalities. For example, when fetal ears or reproductive organs show problems, there may be certain errors. If there is an error in the examination, or if the examination process is not clear, you can do another exclusion, or do further examination.
