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

From the day of pregnancy, pregnant women are full of expectations for the baby in their belly, and mothers often imagine what the baby will look like after birth. With the improvement of modern medical technology, many mothers can't wait to see the fetus in their belly, and will choose to do four-dimensional color ultrasound. It can not only satisfy their curiosity about the fetus in their belly, but also let them know the growth and development of the fetus. So, how many months of pregnancy is it best to do four-dimensional color ultrasound?

Four-dimensional color ultrasound exceeds the limitations of traditional ultrasound. In addition to displaying real-time dynamic images of the fetus in the abdomen, it can also observe the growth and development of the fetus in the uterus from multiple directions and angles, and examine the fetal body surface, such as cleft lip, spina bifida, and maldevelopment of the brain, kidneys, heart, and bones, etc., providing an accurate scientific basis for the early diagnosis of congenital fetal body malformations and congenital heart diseases.

Four-dimensional color ultrasound is a very safe examination technology. If used for fetal malformation examination, it will not cause any harm to the fetus. Traditional B-ultrasound is ultrasonic transmission, while four-dimensional color ultrasound does not have ionizing radiation and electromagnetic radiation. It is a sound wave transmission, which does not cause any harm to human tissue. Expectant mothers can undergo the examination with confidence without worrying about whether it will cause radiation damage.

It is most appropriate for pregnant mothers 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 period, the baby's size and amniotic fluid are moderate, and there is a large space for activities 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.

Nowadays, pregnant women will definitely choose to have a four-dimensional color ultrasound examination so that they can understand the growth and development of the baby in their belly in time, so as to timely understand the problems of the fetus, whether there is any lesion, etc. According to the above introduction, female friends also know that they need to choose the correct and appropriate time to undergo this examination.
