What does a 4D color Doppler ultrasound check for pregnant women?

Four-dimensional color ultrasound is the most advanced ultrasound technology available today. It can observe the dynamic image of the fetus in the uterus of pregnant women and can more clearly observe the growth and development of the fetus. Most pregnant mothers choose to do four-dimensional color ultrasound in the second trimester. But do you know what the four-dimensional color ultrasound checks? Next, let’s take a look at what color Doppler ultrasound can check during pregnancy.

What does four-dimensional color ultrasound examine? Four-dimensional color ultrasound is four-dimensional imaging technology (4D), which can vividly and stereoscopically display the three-dimensional structure and dynamics of internal organs, and observe the three-dimensional structure in real time, while the previous two-dimensional imaging technology can only display a certain aspect of the internal organs. In the field of obstetrics and gynecology, four-dimensional color ultrasound can be used to perform color ultrasound examinations on the fetus, which can display the color, face, and internal organs of the fetus in three dimensions, and even the condition of the fetus in the pregnant mother can be observed; malformations of the fetus, such as cleft lip and palate, cleft palate, abnormal bone growth, cardiovascular malformations, etc. can be diagnosed at an early stage.

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. 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. However, four-dimensional color ultrasound is not omnipotent. For example, it cannot detect deafness or cataracts in newborn babies.

The above is the relevant content about what the four-dimensional color ultrasound during pregnancy checks. In addition, 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 developing rapidly around the 24th week. 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.
