Four dimensional color Doppler ultrasound baby like “hide and seek”? The pregnant mother knows these problems in advance, otherwise it will be wasted

Four dimensional color Doppler ultrasound is based on three-dimensional color Doppler ultrasound, adding time dimension parameters, to help doctors better observe the real-time activities of the fetus, to understand the situation of the fetus, to investigate fetal malformations. < / P > < p > after many pregnant mothers are pregnant, they can’t help but feel headache when they look at a lot of tests to be done. Among them, there are several items to eliminate deformities. Among them, there is a test called four-dimensional color Doppler ultrasound, which is carried out between 22 and 26 weeks of pregnancy. < p > < p > Feifei will soon be 22 weeks pregnant, and she will have a four-dimensional color Doppler ultrasound, but she is a little tangled. It turns out that she has done NT examination before, and the baby has no problem, so she doesn’t want to do 4D color Doppler ultrasound. < / P > < p > she told her idea to a friend who was already a mother. Friends said to her: “nt and four-dimensional color Doppler ultrasound is not the same, regardless of the inspection of things are not the same, just the interval of time is a large part.” Looking at Feifei’s incomprehensible appearance, the friend then explained: “NT is an early Tang sieve, which can only check neural defects, mainly looking at chromosomes, but four-dimensional color Doppler ultrasound can check fetal morphology and structural defects.” < / P > < p > the examination time of four-dimensional color Doppler ultrasound is between 22 and 16 weeks of gestation. Doctors suggest to check again after 24 weeks of gestation, because there are certain differences in fetal development. Some fetuses develop later, and the visceral development of fetuses is initially mature after 24 weeks. < / P > < p > in addition, although the four-dimensional color Doppler ultrasound can be done all day, it is better to choose the time when fetal movement is more frequent to do the examination, because this four-dimensional color Doppler ultrasound needs the cooperation of the baby, so it is convenient to choose the time when the baby is active to cooperate with the examination. < / P > < p > and pay attention not to fasting. If there is blood drawing before, you can take some food, and then you can take some chocolate for your baby to replenish energy and become more active. < / P > < p > through 4D imaging technology, four-dimensional color Doppler ultrasound breaks the limitation of ultrasound, and can see the baby’s every move and observe the baby’s development in an all-round way. The general examination time is 10-30 minutes. < / P > < p > four dimensional color Doppler ultrasound can see the specific activities of the baby, so it is natural to see the sex of the fetus. But doctors are professional, and they don’t reveal the sex of the fetus. < / P > < p > and you don’t have to rely on computer imaging to see the baby’s secondary sexual signs, because doctors avoid the lower body and don’t image on the computer. < / P > < p > and the four-dimensional color Doppler ultrasound does not need pregnant mothers to hold urine in advance. When going to the examination, do not wear a one-piece suit, and choose the upper and lower separate jacket and pants, which is more convenient for inspection. < / P > < p > “I am a candy mom, a learning and growing treasure mother.
