Does the baby have any problems if the four-dimensional test is passed?

Generally speaking, four-dimensional color ultrasound can reveal major malformations in the fetus, such as congenital heart disease, cleft lip and palate, hydrops fetus, congenital fingers (toes) and external auditory canal malformations. So, if the four-dimensional test is passed, will the baby be fine?

The passing of the four-dimensional ultrasound does not necessarily mean that the baby is fine. The four-dimensional color ultrasound can check the fetal facial deformities, nervous, digestive, urinary systems, etc., but it cannot detect all deformities. Under normal circumstances, there will be no problems, but there are exceptions. For example, if the pregnant woman is malnourished in the late stage, the baby's nutrient absorption is insufficient, which is easy to cause abnormalities. Therefore, relevant routine examinations are still necessary.

If the mother's amniotic fluid depth and amniotic fluid index are normal, then the possibility of deformity is small. Of course, it may also occur in the late stage of malnutrition, so it is necessary to conduct regular prenatal examinations, generally a routine physical examination every ten days, and an ultrasound examination should be performed when the pregnancy is more than 30 weeks. You should relax at ordinary times and don't worry.

What is 4D Color Doppler Ultrasound?

Four-dimensional color ultrasound is a type of color ultrasound examination. In addition to the functions of general B-ultrasound, it can also perform three-dimensional imaging of the fetal head and face, and can clearly show the eyes, nose, mouth, jaw, etc., which can help doctors to promptly diagnose fetal malformations, including surface malformations, internal organ malformations, and head and face malformations, and can determine the exact position of the fetus in the uterus. In addition, the four-dimensional color ultrasound adds the time dimension parameter based on these functions, which can observe the dynamic movement images of the fetus in real time.

The best time for four-dimensional color Doppler ultrasound

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 Doppler ultrasound is during the 24th to 28th week of pregnancy, because the fetus's brain is in a rapid growth and development stage around 24 weeks. The fetal structure at this stage has been formed, the size of the fetus and the amniotic fluid are moderate, the activity space in the uterine cavity is large, the echo effect of the fetal bones is relatively small, and the image is clearer.

Four-dimensional ultrasound has real-time dynamic effects based on three-dimensional ultrasound. Pregnant fathers and mothers can watch the baby's physiological activities in the mother's belly, such as moving, breathing, swallowing, yawning, and sticking out tongue, through the screen, which is very vivid.

Choosing the best time for four-dimensional color Doppler ultrasound examination can not only leave valuable image records for the child, but also has the more important function of ruling out fetal malformations. Four-dimensional ultrasound examination can be performed at any stage of pregnancy, but the best time is 20-26 weeks of pregnancy. At this time, the main internal organs of the fetus have grown and developed, the amniotic fluid flow is appropriate, and the fetus has entered the abdomen, which is conducive to the screening of fetal malformations.
