How many months is the best to do the four-dimensional

After a woman becomes pregnant, she should undergo prenatal checkups according to the doctor's requirements, especially older women who are more likely to experience certain symptoms, so prenatal checkups are a very important process, and color ultrasound is a very necessary process for pregnant women. Nowadays, four-dimensional color ultrasound is popular, but when is the most appropriate time to do the four-dimensional one? If you want the four-dimensional color ultrasound to be clearer and more conducive to discovering various problems with the fetus, the four-dimensional color ultrasound is a good form. It is generally better to do it six to eight months after pregnancy.

1. When is the best time to do 4D color Doppler ultrasound?

When is the best time to do four-dimensional color ultrasound? Generally speaking, the best time to take a four-dimensional color ultrasound is between 24 and 28 weeks of pregnancy, because the fetus's brain is developing rapidly around 24 weeks. The fetal structure has been formed at this time, the fetus is of moderate size and amniotic fluid, there is more room for movement in the uterus, the fetal bone echo is less affected, and the image is clearer. Choosing the best time to do the four-dimensional color ultrasound examination, in addition to leaving precious imaging records for the child, its more important role is to rule out fetal abnormalities.

2. What does 4D color Doppler ultrasound check?

Four-dimensional color ultrasound is used to observe the growth and development of the fetus in utero, screen for fetal malformations, and provide an accurate scientific basis for the early diagnosis of congenital surface malformations and congenital heart diseases of the fetus.

1. Fetal facial deformities: such as cleft lip and palate; nervous system: anencephaly, hydrocephalus, microcephaly, spina bifida and meningocele.

2. Digestive system: umbilical enterocele, visceral exstrophy, intestinal atresia and megacolon, etc.

3. Urinary system: hydronephrosis, polycystic kidney disease, megacystis, and urethral obstruction.

4. Other deformities: short limbs, conjoined twins, cleft lip, four-chamber heart, polyhydramnios, oligohydramnios, etc.

3. Does color Doppler ultrasound have any effect on the fetus?

Color Doppler ultrasound is an advanced detection method that uses a four-dimensional color ultrasound diagnostic device to obtain three-dimensional images of the fetus in real time. The four-dimensional color ultrasound diagnostic instrument has an excellent ergonomic design. It is an instrument made using the principle of ultrasound. It does not cause radiation such as rays, light waves, and electromagnetic waves, and has no effect on human health. Because four-dimensional color ultrasound diagnosis causes little damage to the human body, can be examined repeatedly, and the diagnosis is rapid and accurate, it has become the preferred imaging diagnostic method in obstetrics and gynecology, providing a more reliable basis for medical treatment and scientific research, and has become an indispensable auxiliary diagnostic tool.
