When it comes to the two specialized terms ‘four-dimensional’ and ‘major fetal anomaly screening’, they may be very unfamiliar to many people, but they are very familiar to expectant mothers; some people may understand these terms, but do not understand what they actually mean? And do not understand the relationship between them. Then, which is better, four-dimensional or major fetal anomaly screening?

Which is better, four-dimensional or major fetal anomaly screening?

The purpose of fetal anomaly ultrasound is mainly to eliminate the possibility of skin, organ, endocrine, and central nervous system development abnormalities during the baby’s development. The examination methods include four-dimensional color Doppler ultrasound examination, three-dimensional color Doppler ultrasound examination, systematic color Doppler examination, Down syndrome screening, chromosome examination, etc.

　 　 　 Four-dimensional color Doppler ultrasound is a method of fetal anomaly screening, and it is a key examination method to evaluate whether the fetus has significant physical, skin, organ development abnormalities and abnormal movement function during the middle and late stages of pregnancy. In other words, the four-dimensional color Doppler ultrasound examination is a method of fetal anomaly screening during pregnancy, but fetal anomaly screening not only includes four-dimensional color Doppler ultrasound examination, but also contains more systematic, comprehensive, and detailed content. The two cannot be directly compared. After undergoing various systematic examinations during pregnancy, if no significant developmental abnormalities of the fetus are found, the fetus is generally healthy.

What is the difference between four-dimensional and major fetal anomaly screening?

Major fetal anomaly screening is an examination that pregnant women need to undergo within a certain time period, and this examination can be a four-dimensional color Doppler ultrasound examination. Therefore, ‘four-dimensional’ is included in ‘major fetal anomaly screening’.

The prenatal examination is very important, and the necessity of fetal anomaly ultrasound in the whole process of prenatal examination is even more prominent. As its content is very extensive and comprehensive, it is a key way to avoid the birth of malformed babies. Therefore, all expectant mothers should pay close attention and attach great importance to the examination of major fetal anomaly screening.
