Four-dimensional color Doppler ultrasound to see faces divided into men and women

Four-dimensional color Doppler ultrasound is an advanced B-ultrasound technology, which can be used to check the growth and development of fetus in uterus. The state explicitly prohibits the use of B-ultrasound to detect the sex of the fetus. Some mothers want to distinguish a baby boy from a baby girl by looking at their faces. So, can four-dimensional color Doppler ultrasound distinguish between male and female babies? Let me introduce you.

Four-dimensional color Doppler ultrasound is used to detect and screen fetal malformation, which provides accurate scientific basis for early diagnosis of fetal congenital body surface malformation and congenital heart.

1, fetal facial deformity: such as cleft lip and palate; Nervous system: no cerebral malformation, hydrocephalus, microcephaly, spina bifida and meningocele.

2. Digestive system: omphalocele, visceral eversion, intestinal atresia, Hirschsprung's disease.

3. Urinary system: hydronephrosis, polycystic kidney, huge bladder and urethral obstruction.

4. Other deformities: short limb deformity, conjoined deformity, cleft lip, four cavities, polyhydramnios, oligohydramnios, etc.

Four-dimensional color Doppler ultrasound surface imaging for obstetric examination can not only observe the process of fetal growth, but also visually see the activities of the fetus in the mother, such as breathing and movement, including whole body movement, limb movement and even tiny swallowing movements of the fetus. Doctors can also observe whether the tension of the fetus is good through four-dimensional color Doppler ultrasound.

Four-dimensional color Doppler ultrasound can tell the sex, but it is forbidden by the state, so doctors will not tell the sex of the fetus. Some expectant mothers want to see men and women from the faces of four-dimensional color Doppler ultrasound, which is also impossible. Although they can see the appearance of the fetus, it is difficult to simply see whether it is male or female, so the five methods of four-dimensional color ultrasound can distinguish men from women by looking at their faces.

When to do four-dimensional color Doppler ultrasound, the best time to do four-dimensional color Doppler ultrasound varies from person to person, and the results will be different with different needs. Generally speaking, pregnancy can be divided into three stages: pre-pregnancy (65438+10-March), middle pregnancy (March-June) and late pregnancy (June-September). The results of four-dimensional color Doppler ultrasound in these three periods are also different. The best time to do four-dimensional color Doppler ultrasound is 5-8 months (20-28 weeks) of pregnancy, because the limbs and main organs of the fetus have all developed during this period, and amniotic fluid is more suitable for fetal malformation screening. However, due to the individual differences of pregnant women, the specific time of the individual should also contact the doctor and follow the doctor's advice.

1. Take a picture of the baby's whole body: At this time, you can choose to do four-dimensional color Doppler ultrasound in the first trimester. At this time, the baby is still young, and you can take pictures of the baby's whole body through the instrument. It is worth reminding that it is not recommended to do four-dimensional color Doppler ultrasound in June 5438+0-February. It is controversial to do four-dimensional color Doppler ultrasound during this pregnancy.

2. In order to check the baby's external defects: At this time, you can choose to do four-dimensional color Doppler ultrasound in the second or third trimester. At this time, the baby's body has developed to a certain extent, and it is impossible to take pictures of the baby's whole body, but the shape of a certain part of the baby can be observed.

Wonderful recommendation:

Does amniocentesis in ectopic pregnancy lead to dyspnea by four-dimensional color Doppler Down's screening for varicose veins and false contractions? Does the baby move during contractions? Is it accurate for B-ultrasound to check the sex of the fetus and the symptoms of pregnant boy 100%?
