In fact, color Doppler ultrasound examination for major fetal malformation screening is based on two-dimensional ultrasound. Generally, after the four-dimensional ultrasound examination is completed, three-dimensional ultrasound or four-dimensional color Doppler ultrasound can be constructed. In this way, ideal inspection results can be obtained. If there is no abnormality in the two-dimensional color Doppler ultrasound examination, no obvious abnormality will be found in the three-dimensional or four-dimensional examination. Therefore, for pregnant women between 20 and 24 weeks of gestation, an ultrasound examination for anatomical abnormalities is necessary.

Pregnant women should keep calm when doing four-dimensional color ultrasound to avoid large mood swings, and there is no need to check on an empty stomach. Before the examination, you can increase the intensity of exercise appropriately. These are beneficial to the change of the fetal posture and facilitate a more detailed examination of the fetus.

Generally, an ultrasound examination for malformation screening should be performed at 22-24 weeks of pregnancy. If the ultrasound screening shows that the fetus is normal, a four-dimensional color ultrasound examination can be performed around 26 weeks of pregnancy. The difference between ordinary B-ultrasound and four-dimensional color ultrasound lies in the different software used. The four-dimensional color ultrasound can display images in three dimensions, allowing you to see the condition of the fetus more vividly, and you can take photos or record videos for storage. However, at present, most hospitals rarely perform four-dimensional color ultrasound because of the large number of patients and the time-consuming nature of the examination. If you want to do a four-dimensional color ultrasound, you can go to a hospital that performs this test for testing.

At this time, pregnant women need to pay attention to the fact that they will not be affected by intestinal gas when doing four-dimensional color ultrasound examination, and they do not need to do it on an empty stomach. On the contrary, during the examination, due to the discomfort of the fetus's posture or fetal inactivity, the examination time will be longer and the energy consumption will be greater. Remember to bring food to help pregnant women replenish their energy.

It is best to do four-dimensional color ultrasound twice during the entire pregnancy. The first time is when the pregnancy is around 22 weeks. The four-dimensional scan at this time is needed to check whether the fetus's face and limbs have any deformities, which is what doctors often call major fetal malformation screening. The second four-dimensional color Doppler ultrasound should be done around 28 weeks of pregnancy. At this time, each organ of the fetus has been fully developed, and the main purpose is to check the malformation of each organ of the fetus. Therefore, these two four-dimensional color ultrasounds are very important for detecting fetal malformations.
