During pregnancy, pregnant women need to undergo B-ultrasound to observe the condition of the fetus in the mother's body. However, regular B-ultrasound can only display a certain section of the fetus, while 3D ultrasound can provide a more intuitive and three-dimensional observation of the fetus's condition, including the head, trunk, and even visceral activity. When is it suitable to do 3D ultrasound? Does 3D ultrasound have an impact on the fetus?
When is the best time to do the first 3D ultrasound
The first 3D ultrasound is usually performed between 22-24 weeks of pregnancy. The main purpose of this ultrasound is to observe whether the baby has any deformities, especially for the examination of cleft lip. In addition, the continuity of the spine and visceral condition can also be examined. At this time, it can also be seen that the most important aspects of the baby's development include biparietal diameter, head circumference, abdominal circumference, and femur length.
When is the best time to do the second 3D ultrasound
The second 3D ultrasound is usually performed between 28-30 weeks. As the baby has grown much older than during the first 3D ultrasound, they can see the parts that were not visible during the first 3D ultrasound more clearly. During the second 3D ultrasound, the mother's placenta, amniotic fluid, and baby's development can also be understood.
The impact of 3D ultrasound on the fetus
The function of 3D ultrasound is actually to observe whether the fetus is growing healthily. Nowadays, many pregnant women pursue fashion by using 3D ultrasound to "take pictures" of their babies, and even make short videos to capture the appearance of their babies in the uterus. But doing more 3D ultrasound is harmful to babies. Because 3D ultrasound is achieved through ultrasound, which is a type of energy that can treat diseases, excessive use of ultrasound can cause harm to the human body, let alone delicate fetuses.
Three dimensional color ultrasound plays an important role in observing whether the fetus is developing healthily in advance, so it is important for mothers to understand when it is best to do three-dimensional color ultrasound. However, expectant mothers should not ignore the frequency and duration of 3D ultrasound.
