How many months of pregnancy is the best for four-dimensional color Doppler ultrasound

Because four-dimensional color ultrasound technology can display the development of the fetus more clearly and three-dimensionally, it can perform fetal malformation examinations, and pregnant mothers can also meet their babies in their bellies earlier. Therefore, four-dimensional color ultrasound has become a pregnancy check that pregnant women are very keen on, but four-dimensional color ultrasound cannot be done at any time! So, at which month of pregnancy is it best to do four-dimensional color ultrasound? Find out through the following article.

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.

Is it necessary 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.

Will four-dimensional color ultrasound have any impact on the fetus?

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.

What is the difference between four-dimensional color ultrasound and ordinary color ultrasound?

Black and white ultrasonic diagnostic technology uses grayscale modulation to display the sonogram of the sound beam scanning the human body section. B-ultrasound has only one probe and can generally only examine the cavity. Therefore, its diagnostic range of diseases is limited, and the flat static imaging is fuzzy and prone to misdiagnosis.

Three-dimensional color ultrasound is a high-definition black and white B-ultrasound plus color Doppler. It has all the functions of traditional B-ultrasound and can capture images of different gestational weeks. Although it is three-dimensional imaging, the image is still observed in the form of a picture, the observation surface is partial, and the clarity is slightly worse than that of four-dimensional color ultrasound, so the detection is not comprehensive and accurate enough.

At which month of pregnancy is it best to do a four-dimensional color ultrasound? I believe you have got the answer through the detailed answers in the above article. Because four-dimensional color ultrasound uses ultrasound to examine and there is no radiation, it does not cause any harm to the fetus or pregnant women. The best time to check on single and twin babies is different. You can not only feel the baby's breathing and movement, but also witness their every move and cute appearance with your own eyes.
