What is the difference between four-dimensional color Doppler ultrasound and large row deformity?

To a large extent, people equate four-dimensional color Doppler ultrasound with large row abnormality examination. While doing four-dimensional color Doppler ultrasound, there will also be large row abnormality examination items. Now the two kinds of examinations are merged into one item. When doing four-dimensional color Doppler ultrasound examination, it is not only necessary to clarify whether the growth and development of the fetal body has reached normal standards, but also to clarify whether the fetal internal organs are normal. In addition, it is necessary to monitor the fetal heart. Generally, when doing four-dimensional color Doppler ultrasound examination, it will involve the liver and kidney function examination of the fetus to make sure whether there is abnormal development of the fetus, so four-dimensional color Doppler ultrasound is also regarded as large row abnormality examination.
