How many months of pregnancy is it best for pregnant women to do four-dimensional color ultrasound

With the advancement of science and technology, B-ultrasound, which used to be black and white, has now developed into color ultrasound. Four-dimensional color ultrasound can clearly see the baby in the belly and feel the baby's breathing. However, some mothers may have this question: At which months of pregnancy is it best for pregnant women to do four-dimensional color ultrasound? Today, the editor will introduce to you at which months of pregnancy is it best for pregnant women to do four-dimensional color ultrasound.

As long as there is an appropriate amount of amniotic fluid, four-dimensional color ultrasound can be performed. However, the examination is affected by many factors such as fetal position, different gestational stages, placenta, amniotic fluid, etc. Therefore, it is recommended that pregnant women have better examinations during the following pregnancy periods. The best period is 12-30 weeks (the best time to obtain facial and visceral structure images is 20-28 weeks).

The first check-up can be done around 14 weeks of pregnancy.

During this period, the overall image of the fetus including the head, body and limbs can be displayed on the same section. During the four-dimensional real-time examination, the coordination of the overall movement of the fetus can be observed. However, the display effect of the fetal face is poor and the internal organs are not clearly displayed.

The second check can be performed around 22 weeks of pregnancy.

At this time, the fetus is larger than in the previous period, and the overall structure of the fetus cannot be shown on the same image, but the local structure and movement status of the fetus are clearer than before. Severe fetal malformations can be found: anencephaly, severe encephalocele, severe open spina bifida, severe pleural wall defect and visceral eversion, single-chamber heart, lethal chondrodysplasia, etc.

The third check can be performed around 28 weeks of pregnancy.

During this period, the subcutaneous fat of the fetus is fuller than above, the facial expressions are richer, and the various parts of the fetus are clearer than in the previous period. Not only is the diagnosis of the above-mentioned malformations clearer, but also the various facial expressions of the fetus, such as sucking fingers, drinking amniotic fluid, yawning, crying, etc. are clearly visible. In particular, some fetal malformations may not appear until the second or third trimester, so ultrasound examination in the third trimester is essential.

The above is what I want to introduce to you about the best months for pregnant women to do four-dimensional color ultrasound. I hope my sharing will be helpful to all pregnant mothers. The editor reminds all pregnant mothers to pay more attention to their physical health in daily life and go for regular physical examinations. The editor also wishes everyone good health.
