Ultrasound is black and white, which makes it difficult to see the true state of the fetus in the belly. Therefore, ultrasound has emerged, which allows expectant fathers and mothers to see the fetus more clearly through ultrasound. However, like ultrasound, color ultrasound also has radiation, so it cannot be done frequently. So, can I have a color ultrasound at 26 days pregnant?
26 days of pregnancy is not suitable for undergoing a 4D ultrasound. Generally speaking, 24-28 weeks of pregnancy is the best time to take a 4D ultrasound because around 24 weeks of pregnancy is the period of rapid brain development. During this period, the fetal structure has already formed, the size of the fetus and the amniotic fluid are moderate, and there is a large space for movement in the uterus. The impact of fetal bone echoes is relatively small, and the images are relatively clear.
The most common is four-dimensional color ultrasound, which is a type of ultrasound examination. In addition to the functions of general color ultrasound, four-dimensional color ultrasound can also perform three-dimensional imaging of the fetal head and face, which can clearly display the status of the eyes, nose, mouth, chin, etc. It can assist doctors in directly diagnosing congenital abnormalities of the fetus, including surface deformities, visceral deformities, and head and face deformities, and can determine the precise position of the fetus in the uterus. In addition, four-dimensional ultrasound also adds time dimension parameters on the basis of these functions, which can observe the dynamic activity images of the fetus in real time.
Generally speaking, four-dimensional ultrasound can detect major fetal abnormalities, such as congenital heart disease, cleft lip and palate, hydrops, polydactyly, and external ear deformities in newborns. But four-dimensional color ultrasound is not omnipotent, for example, newborn deafness, cataracts, etc. cannot be detected.
