How to see the sex of the fetus from the four-dimensional color Doppler single? The following are some color Doppler data and the corresponding fetal sex, which can be used for the entertainment of prospective parents, but don't take it too seriously. After all, it is unscientific to look at the sex of the fetus from the color Doppler data. (w stands for week, which is the first letter of English week; D stands for days, which is the first letter of day) B-ultrasound data 1, 7W+ 1D: gestational sac 2.9 1.9, it's a boy. 2.9W+4D ultrasound data: 46.630.2mm gestational sac twins are girls. 3, 60 days of B-ultrasound data: gestational sac size is 3.6 1.6mm, and it is a male baby. 4.5W+6D ultrasound data: gestational sac size is 25mm 1 1mm, male baby. 6, 46 days of B-ultrasound data: gestational sac 20mm× 17mm× 17mm, female baby. 7.7w+ 1D ultrasound showed that the gestational sac was 3220mm and it was a female baby. B-ultrasound data over 8 and 7 weeks: A 3.82.3cm gestational sac was found in the uterus, which was a male fetus. More than 9 or 8 weeks, it's B-ultrasound. Gestational sac 19mm 10mm, it's a baby boy. 10, at 8 weeks, it was 4 128mm, and it was also a female baby. 1 1 and 62-day B-ultrasound data: intrauterine gestational sac 2.6 1.8 is a boy. 12 and 50 days of B-ultrasound data: the gestational sac is 35 mm and 27 mm is a female baby. 13, gestational sac size: 35mm×34mm×28mm, it is a female baby. 14, gestational sac size: 18mm × 16mm × 8mm, it is a female baby. 15, gestational sac length 4420mm, it is a boy.
The difference between three-dimensional color ultrasound and four-dimensional color ultrasound. At present, the main color Doppler ultrasound is four-dimensional color Doppler ultrasound. The difference between three-dimensional color Doppler ultrasound and four-dimensional color Doppler ultrasound mainly lies in a "time dimension", that is to say, three-dimensional color Doppler ultrasound is a picture, which is static, while four-dimensional color Doppler ultrasound is a video, which is dynamic and allows pregnant mothers to see a series of actions of the fetus, so four-dimensional color Doppler ultrasound can only be a photo at a certain point in time, and it can be made as continuous as DV and can be burned into a CD. Three-dimensional color Doppler ultrasound has the same function as high-definition four-dimensional color Doppler ultrasound, and high-definition four-dimensional color Doppler ultrasound is more accurate. Three-dimensional color Doppler ultrasound focuses on observing whether the internal organs are deformed and excluding structural deformities. Four-dimensional color Doppler ultrasound also observed whether the motor nervous system was normal and whether the movements were coordinated.
