During pregnancy, 4D ultrasound is a necessary examination that provides a more intuitive and accurate view compared to B-ultrasound. Especially for fetal malformations, it is clearer. However, there is a time limit for doing four-dimensional ultrasound, and it cannot be done at any stage of pregnancy. When should we do four-dimensional ultrasound?
Four dimensional color ultrasound is usually performed between 24-28 weeks of pregnancy because the fetal brain is in a period of rapid development, and the fetal body is fully developed during this period. The size of the fetus is suitable for the amniotic fluid in the abdomen, and the fetal movement space in the uterus is also relatively large, which will not have a significant impact on the echo of the fetal bones. The images seen are also very clear, and the examination results will be better.
Four dimensional ultrasound is a real-time dynamic effect generated on the basis of three-dimensional ultrasound. By doing four-dimensional ultrasound, expectant mothers and fathers can better see the fetus swallowing, breathing, yawning and other movements in the mother's womb.
When doing four-dimensional ultrasound, pregnant women do not need to hold their urine or go on an empty stomach. In fact, the results detected by pregnant women after eating food will be more obvious. By doing four-dimensional color ultrasound, we can understand the development of the fetus and see if there are any abnormalities in the heart, brain, face, and spine.
