Compared with other ultrasound examinations, the four-dimensional color Doppler ultrasound of the born boy can observe the dynamic movement inside the human body in real time, and of course, it can accurately see what the fetus is like, so as to determine the sex of the fetus. After 12 weeks of pregnancy, the fetal development began to be different. Generally, the female baby's buds will develop separately into the inside, while Bao's will start to protrude out of the image and develop into a small penis, which can be clearly seen by four-dimensional color Doppler ultrasound after 15 weeks. The most accurate way to see men and women in the spine.
When doing four-dimensional color Doppler ultrasound, because doctors will not tell, and will take the initiative to avoid the sex characteristics of the fetus, so there are many ways to see men and women through four-dimensional color Doppler ultrasound or B-ultrasound data.
1, gestational sac size depends on men and women
It is rumored that the difference between the length and width of the gestational sac is more than double, so it is likely to be valuable. If the length and width are equal, or there is not much difference, it is likely to be a female baby. But in fact, there is no scientific basis for this, because the size of gestational sac measured by B-ultrasound is mainly used to estimate the gestational age, and the defects in fetal development can be detected in time according to the changes of data.
This is a four-dimensional B-ultrasound image taken when I was 24 weeks pregnant. Is this image taken? 2, the shape of the gestational sac shows that the male and female spines are beaded boys and girls.
It is rumored that the gestational sac is shaped like eggplant, or it is long, so it is more likely to be pregnant with treasure; And if the gestational sac is oval or round, it is likely to be a female baby. Psychologists tell us that there is no scientific basis, because the shape of the gestational sac is determined by its content and will change its shape during pregnancy. In addition, the position of implantation is different, and the shape of gestational sac is different from the direction and angle of B-ultrasound.
? 3, double top diameter femur length to see men and women
It is said that boys have big heads and short legs, while girls have long legs and small heads. Therefore, you can subtract the femur length from the double top diameter, and the data obtained is greater than the son, and vice versa.
Although there is a certain relationship between the sex of the fetus and the femoral head length of biparietal diameter, we can't judge the sex of the fetus simply by the femoral head length of biparietal diameter, because biparietal diameter and femoral head length are only an index of fetal development, and we can't see the sex of the fetus, but we can use biparietal diameter to calculate the weight of the fetus.
Four-dimensional color Doppler ultrasound of a born boy: seven-month four-dimensional color Doppler ultrasound picture. Is it a boy or a girl? Girls and boys are the same. Compared with other ultrasound examinations, four-dimensional ultrasound can observe the dynamic movement inside the human body in real time and accurately distinguish the sex of the fetus. Although four-dimensional color Doppler ultrasound can clearly see the sex of the fetus, in order to avoid revealing the sex of the fetus during the examination, the doctor will actively avoid the sex characteristics of the fetus and the lower body.
How many treasure mothers have done four-dimensional identification, that is, boys are born girls with clenched fists, and they are usually boys.
You can't see the gender from the results of four-dimensional color Doppler ultrasound. Only when the doctor is in front of the computer and gives you four-dimensional color Doppler ultrasound, he knows it, but he won't reveal the formula of seeing men and women in a big row.
Can B-ultrasound make a mistake when doing sex? Have any of you done B-ultrasound, tested sex, and showed a boy, but it turned out to be a girl? Is there such a thing?
Generally, the results of B-ultrasound are not allowed to identify the sex. However, 99.9% identified by B-ultrasound is correct (because it is to see the baby directly). Don't worry. The probability of four-dimensional positive face is high.
Four-dimensional color Doppler ultrasound of a born boy: Who will look at this four-dimensional color Doppler ultrasound? You can tell whether it is a boy or a girl. It is said that the fish with double top diameter minus leg length is a girl, so you should be a girl.
The above is how to see men and women with four-dimensional color Doppler pictures? Related content, is about seven months of four-dimensional color ultrasound pictures, see if it is a boy or a girl? Sharing. After reading the four-dimensional color Doppler ultrasound of the born boy, I hope this will help everyone!
