Four dimensional examination is a crucial item in the overall aspect of pregnancy examination. Through four-dimensional examination, the development of the fetus can be clearly observed and the possibility of fetal malformation diseases can be ruled out. However, some people may be curious because they are new to this knowledge. So, what is the concept of four-dimensional examination at 22 weeks?
During the 22 week four-dimensional examination, the fetal weight had already increased to around 350 grams. If there were no unexpected circumstances, the fetal length would be around 19 centimeters, and the eyebrows and eyes of the fetus could be clearly seen during the examination. Nails would also grow on the fingers, but because the subcutaneous fat had not fully developed, the fetal skin would appear bright red and wrinkled, resembling that of an elderly person.
During the four-dimensional examination at 22 weeks, the uterus, even a small house for the fetus, is very spacious. In this space, the fetus can move freely and change its posture, and there will be some small movements in its hands, eyes, and nose, which is quite cute.
The best time for four-dimensional examination is also qualitative, usually around 20 to 28 weeks. Through four-dimensional examination, the health condition and limb development of the fetus can be clearly observed. The appearance of the baby that parents are most concerned about will also be revealed for the first time. However, before the examination, it is necessary to pay attention to the physical condition of the pregnant woman, and it must not be examined in an unhealthy state, otherwise the fetus will not have obvious signs of movement.
