What is the difference between three-dimensional and four-dimensional examination during pregnancy? Three major differences pregnant women should understand, baby appearance meet early

After pregnancy, the most headache for pregnant mothers is the various examinations, because they do not know when to check, do not understand what tests should be done, which inspection will be better, especially the pregnancy is very important color Doppler ultrasound, do not understand the difference between three-dimensional and four-dimensional, so they will be very entangled. < p > < p > 1. Three dimensional color Doppler ultrasound is static and can only see the picture of a certain section of the fetus, while the four-dimensional color Doppler ultrasound is dynamic, which can see a series of fetal movements, such as tooting the mouth and sticking out the tongue, which can be clearly seen, and can also be engraved on a CD to leave a memorial for the fetus. < p > < p > 2. Three dimensional color Doppler ultrasound is mainly used to observe whether fetal organs are abnormal, so as to exclude fetal structural abnormalities. However, four-dimensional color Doppler ultrasound can not only screen out fetal malformations, but also see whether some internal fine structures are normal. < / P > < p > 3, four-dimensional color Doppler ultrasound can show the fetal facial imaging and the development of various organs, the clarity is much higher, you can clearly see the difference, the photo is not as fuzzy as three-dimensional, which is very good for pregnant women who want to see what the fetus looks like, because they can clearly take photos to satisfy their curiosity. < / P > < p > no matter three-dimensional or four-dimensional radiation does not have obvious harm to the human body. Its principle is that through the transmission of ultrasonic coupling agent, we can judge whether the fetus is abnormal, such as cleft lip, cleft palate, abnormal bone development, and so on, so as to make early diagnosis, so as to lay a good foundation for the future. < / P > < p > in fact, 3D and 4D are not of great diagnostic significance, because fetal malformation diagnosis still needs two-dimensional support. We all make some changes and upgrades on the basis of two-dimensional to meet the screening requirements of doctors. < / P > < p > we use two-dimensional images, that is, black-and-white, when we take pictures of the fetus or blood flow, it is not what we think of as “big color TV”. < / P > < p > of course, there is also a very important point of four-dimensional color Doppler ultrasound, which is beneficial to pregnant women with thick abdominal wall. It should be relatively clear when looking at it, much clearer than that of three-dimensional ultrasound, which can also be felt by pregnant women when doing color Doppler ultrasound. < / P > < p > in fact, it is still recommended that conditional pregnant women choose four-dimensional color Doppler ultrasound directly. Although the price is higher, there is not a little bit of poor definition. Obviously, the difference can be seen. Moreover, some advanced four-dimensional machines are stereoscopic in the process of upper blood flow, which can be said to be very advanced. < / P > < p > of course, four-dimensional color Doppler ultrasound is also an intrauterine photo. Expectant mothers can see every move of their babies, and doctors can observe the growth and development of the fetus from multiple perspectives, which provides a scientific basis for early diagnosis of fetal malformations. < / P > < p > – I am a small skin nursery classic, a nursery teacher, a working mother, code word for bringing a baby – a multi platform high-quality original author, a fan of pregnancy and childbirth, child care and children’s psychological research – breeding and bringing children is the career of the head of the family.
