What does the four-dimensional test for pregnant women do?

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 development of the fetus. Most pregnant women choose to do four-dimensional color ultrasound in the second trimester. However, many pregnant women are not familiar with this test. So, what can four-dimensional color ultrasound check?

Four-dimensional color Doppler ultrasound refers to looking at the growth and development of multiple organs of a baby in four dimensions, mainly to see whether there are any deformities in the organs. It is a very important fetal anomaly examination in the second trimester of pregnancy. It is necessary for pregnant women to do a four-dimensional color ultrasound examination during pregnancy. And through four-dimensional color ultrasound, we can understand many conditions of the baby.

Through four-dimensional color ultrasound examination, it can be determined whether there are any abnormalities in the limbs and face of the baby in the uterus, whether there are any missing arms or legs, whether there is cleft lip and palate, spina bifida, or some abnormal changes in the bones. During the four-dimensional examination, the growth and development status of each internal organ of the baby can also be seen, such as whether there is organ ectropion, umbilical cord herniation, hydronephrosis, polycystic kidney and megabladder, and the conditions of the brain, heart, etc. can also be determined through four-dimensional color ultrasound examination. If there are any abnormalities, further cardiac ultrasound examination is required.

Four-dimensional color ultrasound examination also has the function of basic B-ultrasound. For example, it can be determined whether the baby in the uterus has the umbilical cord around the neck, the size and position of the baby, and the details of the amniotic fluid of the pregnant woman. If you have a checkup during the second trimester of pregnancy, it is best to do a four-dimensional check-up. Only after you understand the details and have a good understanding of your own mental state, can you rest assured and take care of the baby. In addition, during pregnancy, you should pay attention to adjusting your mentality, relieve stress, and avoid long-term anxiety.

The best time for women to have a four-dimensional color ultrasound is between 24 and 28 weeks of pregnancy, because around 24 weeks of pregnancy is the stage of rapid brain growth and development. 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.
