When is the best time to do three-dimensional color Doppler ultrasound? Clinically, it is mainly to exclude fetal soft tissue malformation, limb malformation and visceral malformation. In short, it is the examination of fetal abnormalities. Therefore, it is recommended to do it between 23 and 28 weeks of pregnancy. However, you need to make an appointment in advance. It is best to make an appointment for color Doppler ultrasound after billing and paying the money, and then go to the hospital for the corresponding examination according to the scheduled time. Three-dimensional color Doppler ultrasound takes a long time, because it takes a long time to understand everything about the internal organs of the fetus from head to toe.
Three-dimensional color Doppler ultrasound is recommended to be performed around 22 ~ 24 weeks of pregnancy. Generally, three-dimensional color Doppler ultrasound can help to observe whether the fetus has some external malformations, which is beneficial to observe whether the fetus develops normally. Generally speaking, pregnant women are advised to have an abnormal examination during pregnancy. You should make an appointment at the hospital in advance, so as not to miss the best opportunity for examination.
Pregnant women generally recommend three-dimensional color Doppler ultrasound at 18-26 weeks. Three-dimensional color Doppler ultrasound can examine fetal face, exclude cleft lip and palate, examine fetal ventricle, echocardiography and other fetal development. But three-dimensional is static and four-dimensional is dynamic, so it is best to do four-dimensional color Doppler ultrasound.
1. Pregnant women are generally examined between 18 and 26 weeks. At this time, they can clearly see the organs of various parts of the fetus, understand the growth and development of the fetus, and at the same time rule out fetal malformations, such as cleft lip and palate, congenital heart disease, digestive tract malformations, and brain abnormalities.
2. But the three-dimensional color is static and the four-dimensional color Doppler is dynamic, so that we can see more clearly and accurately. Four-dimensional color Doppler ultrasound is generally better in 22~24 weeks.
When do pregnant women do three-dimensional color Doppler ultrasound? Pregnant women can do three-dimensional color Doppler ultrasound in the 24th or 25th week, because in the 24th and 25th week of pregnancy, the fetus is not particularly big and there is relatively more amniotic fluid. When detecting three-dimensional color Doppler ultrasound, they can clearly see the development of the fetus in the mother's body, and can effectively rule out major fetal abnormalities, which has a good effect on preventing embryonic abnormalities, especially at the 24th and 5th week of pregnancy.
The definitions of three-dimensional color ultrasound and B-ultrasound are different. B-ultrasound only detects the development of embryos through ordinary ultrasound, and has no function like three-dimensional color ultrasound, so it is impossible to detect abnormal fetuses. In addition, when you are pregnant for about 6-8 weeks, you can do ordinary B-ultrasound, but when you do three-dimensional color ultrasound, you need to be pregnant for a longer time to check it out more effectively.
After the second trimester of pregnancy, it is necessary to go to the hospital for regular check-ups. At this time, doctors will sort out files and record data to provide scientific guarantee for smooth production in the future. The number of new pregnant months is gradually increasing, and it is forbidden for husband and wife to share the same room in the later period. At this time, the surrounding families should also give reasonable care to keep pregnant women optimistic, which is also very helpful for the development of the fetus.
