Biparietal diameter, fetal heart rate, four-dimensional ultrasound report on the data, you can see the fetus “little secret”?

In fact, the real function of four-dimensional color Doppler ultrasound is to eliminate deformity besides taking pictures. Are you still confused about the data of 4D color Doppler ultrasound? Today, I’d like to talk about the examination during pregnancy. < / P > < p > four dimensional color Doppler ultrasound is a four-dimensional imaging technology, which has an additional time dimension on the basis of three-dimensional. Through four-dimensional color Doppler ultrasound, we can intuitively and stereoscopically see the dynamics of the fetus, and observe what the baby is doing in real time, such as eating hands? kicking? Or are you peeing? Therefore, it has the function of photo nostalgia. < / P > < p > four dimensional color Doppler ultrasound can check the fetal development indicators, can screen some fetal congenital diseases, and whether there are malformations. Including limb malformations, meningocele, fetal cleft lip and palate, abdominal wall cleft and other congenital malformations. Therefore, it has the function of fetal teratogenesis. < / P > < p > generally, 22-26 weeks of gestation is the best time to do four-dimensional color Doppler ultrasound, because the fetal brain is in a period of rapid development, which indicates that the major organs of the fetus have matured during this period, and the fetal size and amniotic fluid volume are also moderate. The fetus can fully move in the uterus, and the influence of fetal bone echo is relatively small, so the images are comprehensive and clear It’s clear. < / P > < p > the four-dimensional color ultrasound diagnostic instrument has an excellent ergonomic design. It is an advanced instrument made by using the principle of ultrasound. There is no radiation of rays, light waves and electromagnetic waves, so the worries of these mothers are a little superfluous. Moreover, there is no clear evidence that ultrasound can cause harm to the fetus. < / P > < p > after four-dimensional color Doppler ultrasound, many people will take a look at it for a long time, and also take a picture for people they know, so that they can help to have a look, especially to find out some “secrets” of the fetus, such as male or female? < / P > < p > in fact, we have to admit that four-dimensional color Doppler ultrasound can identify the male and female fetuses, but our country clearly stipulates that it is not allowed to identify the gender of fetuses, unless there are some genetic diseases, it can only identify the gender of fetuses after submitting various applications. < / P > < p > therefore, even if doctors see the gender of the fetus, they will not mention it. At the same time, in order to avoid revealing the sex of the fetus, the key parts of the fetus will be specially treated when making a CD or making a report. < / P > < p > therefore, it is impossible for pregnant mothers to see the fetal gender through the data of four-dimensional color Doppler ultrasound! Whether it’s a boy or a girl in the belly, it’s the crystallization of love, so we should pay more attention to the health of the fetus and whether the development is normal. < / P > < p > this number is an indicator of baby maturity. Determine whether there is cephalopelvic asymmetry, whether it can be delivered smoothly. The fetal biparietal diameter is 8.5cm, and its weight is about 2500g; if it is 9.1cm, its weight is about 3500; when it is about 10cm, its weight is more than 4000g. < / P > < p > the normal fetal heart rate is 120-160 minutes per minute. Some people think that fast fetal heart rate is a girl, while slow fetal heart rate is a boy. In fact, there is no scientific basis for this. There are two possibilities for a normal fetal heart rate to be strong or weak. For example, if the fetus is sleeping, the fetal heart rate will be relatively slow. Of course, we can not rule out the abnormal situation. < / P > < p > the umbilical cord of the fetus is generally immersed in amniotic fluid. If the umbilical cord shadow is seen in the image report, it is very likely that the umbilical cord is around the neck, or it may be obscured by borrow, which needs further observation. The thickness of healthy placenta should be 25-50 mm. According to the difference of chorion and basement membrane, we divided the placental health into four grades: 0, I, II and III. Most of them are grade 0 in the first trimester of pregnancy. In the second trimester of pregnancy, with the maturity of placenta, they begin to develop to grade III. < / P > < p > FL, also known as thigh length, is the value of the longest part of the fetal body. The average doctor will use it to work with BPD to calculate the weight of the fetus. < / P > < p > before the examination, there is no need to have an empty stomach or hold your urine. If you have enough food and drink, you should go to the hospital half an hour in advance. Wear loose, comfortable and convenient clothes on the day of inspection. It’s better to be accompanied by your father to be, so that you can feel the jump of new life together. In addition, it is suggested to take some snacks with you, such as chocolate, candy and so on, for a rainy day. Write at the end < / P > < p > four dimensional ultrasound examination is the only way to pregnancy, pregnant mothers should check on time, do not delay the best time. Finally, I wish you all a good pregnancy. < / P > < p > this article is the original content of the article, focusing on the field of parenting, deepening and improving silently, providing more professional parenting science.
