Generally speaking, pregnant mothers do four-dimensional ultrasound, if found early, fetal malformations are not serious, can be as early as possible to intervene in the treatment; do four-dimensional ultrasound of the best time is 20-22 weeks, the time period, the fetal body structure has been formed, the amniotic fluid and the fetus is the right size, in the ultrasound, the expectant father and expectant mothers are able to see the baby's complete appearance, if the baby's development of the development of the smaller one or two weeks, unavoidable!

To run through what is the difference between two-dimensional ultrasound, three-dimensional ultrasound and four-dimensional color ultrasound, right?
Two-dimensional ultrasound, that is, we often see a plane, and three-dimensional ultrasound it, on the basis of two-dimensional, add more blood flow in, four-dimensional color ultrasound it, in fact, in three-dimensional ultrasound images added to the time dimension; four-dimensional ultrasound, not only look at the growth and development of the fetus, but also more is to look at the structure of the fetus's heart, the construction of the heart of the three-dimensional, in the doctor through the Doppler ultrasound blood flow, the doctor can see the blood flow with the doctor three-dimensional ultrasound hit, the doctor can see the blood flow of the three-dimensional ultrasound. You can see the blood flow and the opening of the valves that the doctor has visualized in three dimensions.
So do not be outside the role of four-dimensional ultrasound after the exaggerated propaganda and thought four-dimensional ultrasound when the omnipotence of it, in addition to pregnant mothers are not recommended to do four-dimensional ultrasound before the third trimester of pregnancy.
