Why do expectant mothers always get ugly babies when they take four-dimensional color ultrasound?

Obviously the expectant father and the expectant mother are both good-looking, so why do pregnant mothers dare not look directly at the first four-dimensional color ultrasound photo of their first baby?

Four-dimensional color ultrasound is a common prenatal check-up during pregnancy, because it can not only achieve the purpose of checking for abnormality, but it is also the "first time" for many expectant fathers and mothers to meet their babies across the screen. But some pregnant mothers are almost "depressed" by their ugly babies when they see the four-dimensional photos of their babies! I couldn't believe it, how could I be pregnant with such an ugly baby?

“When I saw the 4D photo of my baby for the first time, I thought I was pregnant with an alien!”

“The 4D is really the only fun of prenatal care, because you can see What does the baby look like, but I never expected it to be so ugly.”

“The 4D photo of my baby at that time was really ugly, and there was a black thing on the head that I didn’t know what it was.”

I was fully expecting to see a beautiful and cute baby, but I didn’t expect that the appearance index would be so low? In fact, pregnant mothers who have had similar experiences don’t have to worry, because there is a reason why the four-dimensional color ultrasound of the fetus is ugly. After reading these four reasons, maybe the baby's appearance will be "turned around" after birth! Reason 1. Shooting angle problem

Think about how pregnant mothers usually turn left and right when taking selfies to find the most suitable shooting angle, so that they can take the most beautiful photos. Similarly, when performing a four-dimensional color ultrasound on a fetus, the doctor mainly observes the fetus's hands, feet, face, body, etc. to see if there are any deformities, and does not focus on the shooting angle.

So it is normal for the baby in the photo to be blurred into a ball and the face cannot be seen clearly. Reason 2: The impact of amniotic fluid is obvious

You must know that the fetus needs to stay in the womb for ten months before delivery, and is soaked in amniotic fluid every day. When taking a four-dimensional picture, the amniotic fluid is like a magnifying glass, which will affect the growth and development of the baby. Shadowing has an impact.

And during the four-dimensional color ultrasound examination, the doctor will specially enlarge the local image in order to observe the part more clearly. This will cause some parts to look particularly large, for example, many babies have wide and flat noses. . And some parts sometimes appear small, such as squinting eyes. Reason three: There is vernix on the fetus

In addition to the influence of amniotic fluid, the vernix on the fetus will also affect the four-dimensional imaging, causing deviations in the four-dimensional color ultrasound imaging, making the proportions of the fetus' facial features look like unreasonable.

Vernix is ??the white substance on the fetus after birth. It can protect the fetal skin. You must know that vernix is ??not only present at birth, it is produced when the baby is in the womb. Reason 4. Four-dimensional color ultrasound is a dynamic image

The last reason why the fetus is ugly is the imaging principle of four-dimensional color ultrasound. Four-dimensional color ultrasound uses ultrasound technology to shoot and scan the fetus. During the shooting process, the baby is constantly moving, so the impact will continue to change with the baby's movement.

It’s not like we usually take pictures where people stand still, so the details captured are very clear. The moving image itself can only capture a rough outline.

The above four reasons are probably the "culprits" why the fetus looks so ugly on four-dimensional color ultrasound. Don’t be too anxious if the baby looks ugly on the 4D color ultrasound. In fact, it may not be that the baby is not good-looking, but rather that the most beautiful side of the baby is not captured due to technical limitations.

Furthermore, the main purpose of four-dimensional color ultrasound is to monitor and observe whether the baby has malformations. As long as the fetus is healthy, pregnant mothers do not have to worry about temporary appearance problems. Learn about four-dimensional color ultrasound during pregnancy

What are the differences between two-dimensional, three-dimensional, and four-dimensional ultrasound?

First of all, these three "dimensions" are all ultrasound methods used to check whether the baby has deformities. The most accurate one is actually two-dimensional ultrasound. Many large public hospitals still use two-dimensional ultrasound. Fetal malformation screening is done, but only specially professional doctors can see the two-dimensional data clearly.

Three-dimensional color ultrasound is mainly used to check whether there are deformities in the limbs of the fetus. If there are any developmental abnormalities in the limbs of the fetus, it can usually be seen through three-dimensional color ultrasound, which can prevent the birth of a baby with physical disabilities.

Four-dimensional color Doppler ultrasound adds an additional time dimension to three-dimensional color Doppler ultrasound. Its function is to conduct further examination when organ malformations are detected in two dimensions. In addition, the baby's dynamic images can also be shot through four-dimensional, which is like the baby's "zero-year-old movie", which has some nostalgic meaning for the family.

Examination time: Generally, single pregnancy is 23-28 weeks, if twins are 21-23 weeks.

Because the fetal limbs and major organs have all developed during this period, and are of appropriate size, and the amniotic fluid is moderate, the baby can roll around normally, and relevant indicators can be checked from multiple angles.
