When is the best time to have a major fetal anomaly screening during pregnancy?

When it comes to fetal abnormality screening during pregnancy, all pregnant mothers should know about it. In fact, pregnancy fetal malformation screening is to use three-dimensional or four-dimensional color ultrasound technology to check the development of the baby in the belly. So, pregnant mothers-to-be, do you know when is the best time to do a major fetal anomaly screening during pregnancy? Next, let me introduce to you the best time for a major fetal anomaly screening during pregnancy.

In the general sense, fetal anomaly screening refers to color Doppler ultrasound fetal anomaly screening. Generally, pregnant women need to undergo a color Doppler ultrasound examination during the 24th to 28th week of pregnancy. The main purpose is to check whether the baby's development in the uterus is in line with the gestational age; whether the fetus is healthy; whether the limbs, brain, and internal organs are deformed; and the condition of the amniotic fluid and umbilical cord. Pregnant women need to undergo color ultrasound deformity examination at the time specified by the doctor. Currently, there are two examination methods to choose from: three-dimensional color ultrasound or four-dimensional color ultrasound.

The "major fetal anomaly screening" is usually scheduled around 20 to 24 weeks of pregnancy. Most hospitals perform major fetal anomaly screening through three-dimensional or four-dimensional color ultrasound, which can be used to determine whether the fetus is developing normally and whether there are any serious deformities.

Three-dimensional imaging can clearly display the development of the fetus's facial features, limbs, and organs, and can enable early detection and diagnosis of fetal malformations such as cleft lip, cleft palate, skeletal abnormalities, and cardiovascular malformations.

Four-dimensional color ultrasound can even intuitively show the condition of the fetus in the mother's body, fetal movement process, etc. The best time for four-dimensional color ultrasound is generally during pregnancy (20-28 weeks), and amniotic fluid is more suitable for fetal malformation screening. However, due to individual differences among pregnant women, please confirm the specific time with your obstetrician.

There is also a late-onset malformation screening during pregnancy, which is usually scheduled between 28 and 32 weeks of gestation to screen for late-onset malformations such as hydrocephalus. Its function is to supplement the examination of fetal fetal abnormality and fetal growth and development, and to check whether the fetus has abnormalities in the amniotic fluid and umbilical cord.

The above is what I want to introduce to you today about the best time for major fetal malformation screening during pregnancy. You can learn about it, and I hope my sharing will be helpful to you. In fact, the use of four-dimensional color ultrasound or three-dimensional color ultrasound methods can be used to check the baby's health, so the editor recommends that all expectant mothers do this examination.
