How long can I take a 4D scan?

One of the tests that women cannot miss during pregnancy is the four-dimensional color Doppler ultrasound. There are many benefits for women to do the four-dimensional color Doppler ultrasound. Through the test, you can know whether the fetus has any abnormalities, and you can also rule out deformities. Once the possibility of fetal deformity is found, it is better to prepare as soon as possible. So how long can you do the four-dimensional ultrasound during pregnancy?

First of all, generally speaking, women who are 22 weeks pregnant can have a four-dimensional color ultrasound. The examination can determine whether the fetus is normal, whether the fetus has cardiovascular disease, and whether the fetus is likely to be deformed. The four-dimensional color ultrasound examination time is 22-28 weeks of pregnancy, and the examination at this time will be more accurate and reliable.

Secondly, pregnant women are reminded to do a four-dimensional color ultrasound examination at the best time. If the examination is done too early, not only can the tissues not be seen clearly, but it is also impossible to achieve the purpose of eliminating deformities. Moreover, the four-dimensional color ultrasound examination can not only see the condition of the fetus in the belly from all angles and in all directions, but also detect the conditions of cleft lip and palate, heart, bones, etc.

Finally, pregnant mothers need to choose the best time to do fetal anomaly examination, and the four-dimensional color ultrasound examination should be done in a reliable hospital. Once a problem is found, it can be dealt with immediately at the first time, thus reducing the adverse effects on the baby. I hope that expectant mothers can pay attention to the examination during pregnancy and solve the problems as soon as possible if they are found.

Four-dimensional color ultrasound is very popular in society at this stage, mainly for screening fetuses with malformations. Four-dimensional color ultrasound is developed on the basis of two-dimensional color ultrasound and three-dimensional color ultrasound. It can dynamically and three-dimensionally observe the fetal structure, and can leave some medical imaging materials, especially the fetal face, which can allow parents to see the appearance of the fetus. Therefore, some families are very eager to do four-dimensional color ultrasound.

However, when doing four-dimensional color ultrasound during pregnancy, you should pay attention to the time and frequency of the four-dimensional color ultrasound. It is generally recommended to do the four-dimensional color ultrasound around 24 weeks of pregnancy. Because the size of the fetus during this period is relatively suitable, the amniotic fluid flow is relatively abundant, and the fetus has sufficient space to move around in the uterine cavity. By repeatedly observing each structure of the fetus, a complete screening of fetal abnormalities can be carried out, and at this time each structure of the fetus has been fully developed and there is no possibility of misdiagnosis. Therefore, it is recommended to do a four-dimensional color ultrasound at 24 weeks of pregnancy, which is around June. If there is no problem with the four-dimensional color ultrasound, it can usually be done once during pregnancy. If there are other problems, two four-dimensional color ultrasounds may be done.
