How many months of pregnancy is it better to do four-dimensional color Doppler ultrasound

It is very necessary for pregnant women to do four-dimensional color ultrasound. I believe many friends want to know about the question of how many months of pregnancy is better to do four-dimensional color ultrasound. So at which months of pregnancy is it better for pregnant women to do four-dimensional color ultrasound? Next, this article will introduce you to the relevant content in this regard for your reference only. Friends who want to know more about this can take a look!

In addition to allowing expectant parents to "meet" their unborn baby in advance, the most important function of four-dimensional color ultrasound is that it can also perform various examinations on the fetus and detect problems in fetal growth at an early stage, such as cleft lip, spina bifida, etc. In addition, the images displayed by four-dimensional color ultrasound are clearer and more accurate than those of traditional color ultrasound and B-ultrasound. Therefore, for the health of pregnant women and fetuses, it is very necessary to choose four-dimensional color ultrasound examination for prenatal check-ups. Compared with traditional B-ultrasound, four-dimensional color ultrasound has almost no radiation, such as rays, light waves and electromagnetic waves, and has no effect on human health.

At which month of pregnancy is it better for pregnant women to do four-dimensional color ultrasound? It is most appropriate for pregnant women to do four-dimensional color ultrasound when they are 25-28 weeks pregnant, which is about six or seven months pregnant. This is because the fetus's brain is developing rapidly at around 25 weeks. The fetal structure has taken shape at this stage, the baby's size and amniotic fluid are moderate, and there is a large space for movement in the uterus. The fetal bone echo is less affected, and the image will be clearer. If you do a four-dimensional color ultrasound too early, the fetus will be too small and some tissues will not be clearly visible, making it impossible to clearly observe the growth of the fetus and screen for deformities.

Whether the effect of four-dimensional color ultrasound is clear or not is closely related to whether the baby in the belly cooperates. If there is something covering your baby's face, it will be difficult to see facial expressions. The baby's own hands and feet, or the placenta, umbilical cord, uterine wall, etc., are all obstructions. If there is not an adequate amount of amniotic fluid in front of the baby's face, the effect of the four-dimensional color ultrasound will not be very good. Because amniotic fluid is a very good sound-transmitting window, four-dimensional color ultrasound is used to observe the baby through the sound-transmitting window. Therefore, if the mother has less amniotic fluid, the effect of the four-dimensional color ultrasound will be relatively poor.

The above is the introduction about how many months of pregnancy it is better for pregnant women to do four-dimensional color ultrasound. I believe that after reading the above introduction, everyone will have the answer in their mind. Generally speaking, it is better to do a four-dimensional color ultrasound at 6-7 months of pregnancy, because the images taken at this time will be clearer and it will be easier to see whether there are any abnormalities in the development of the fetus. Therefore, it is recommended that pregnant women do four-dimensional color ultrasound at 6-7 months of pregnancy!
