Let’s talk about the original amount of pregnancy.

We know that the fetus has been bubble in the birth of the fetus; when using B-ultrasound, it will show black in the water or aqueous solution; ultrasonic waves have a black; This is the main basis for detecting.

However, there is not only aqueous solution in vivo, which is also aqueous solution of aqueous solution, tissue liquid, urine, inflammatory liquid, etc .;, when B is determined, it must also be able to distinguish the difference between fire water and other liquids. And distinguish between them is to see the volume and site of the liquid.
When the embryo is between three to five weeks, the end of the embryonic individual is very small, and there are many fetal water. At this time, the black is a dark black, and the shell angle length is short, the embryo position is more concentrated. Therefore, the displayed image is a relatively close number of black gardens, and the image is most obvious. However, as the age is increased, the end of the embryo itself increases, and the color of the embryo is grayed.It is not that obvious, and it is also divided; and in the late pregnancy, the fetal skeleton begins to calcify the calcification, and the bone image shown in B-ultrasound is white, and the bones can be seen.

The area of ​​the blood vessel is small, which is generally not easy; the bladder is generally large, and it is not the same position with the uterus angle, and it is easy to see; if it is an uterine inflammation, it is often a large piece of gray, too Can be separated.
