What are the conditions for B-ultrasound examination of early pregnancy

Everyone knows that B-ultrasound is the most basic condition for checking pregnancy, but many women who are just pregnant with their first child do not know much about what this technology requires, so there will be some unnecessary troubles. Therefore, no matter what conditions are required for B-ultrasound examination of early pregnancy, there are other things that need to be understood. Let me give you a detailed introduction below, I hope you can understand it.

How long does it take to do an ultrasound during pregnancy?

Ultrasound examination can only see the gestational sac after 5 weeks of pregnancy, and the detection rate of the gestational sac reaches 100% at 6 weeks of pregnancy. The embryo can be seen at 6-7 weeks of pregnancy. At 49 days of pregnancy, when the diameter of the embryo is 2mm, the primitive heart tube beating can be seen. At 8 weeks of pregnancy, the human shape begins to take shape.

All organs are formed at the 14th week, hair begins to appear at the 15th week, and the uterus is about 16CM at the 16th week.

At the end of the 17th week, the baby's movements are restricted and fetal movements occur. The second scan (to determine gender) is done at the end of week 21. The gender will be known at the end of the 22nd week.

If you do an ultrasound too early, it will not be easy to see the shadow of the gestational sac because it is too small. Not every doctor can make an accurate diagnosis, and it depends on the experience of the person doing the imaging, and the more they do, the better. Ideally, it will be easily visible at 8-10 weeks of pregnancy. And if you do B-ultrasound too early, it will theoretically shock the fragile, newly formed embryo, which is not conducive to embryonic development. It is best to avoid doing B-ultrasound too early or doing it multiple times.

Early pregnancy ultrasound

Conventional B-ultrasound: It is recommended to do the first black and white B-ultrasound monitoring of the fetus after 7 weeks of pregnancy. There are three purposes: 1. To determine whether it is a normal pregnancy or an abnormality. If it is an intrauterine pregnancy, the accurate due date can be calculated based on this; however, there may also be problems such as ectopic pregnancy or hydatidiform mole, which must be dealt with in a timely manner once discovered. 2. Determine the number of embryos. 3. At this time, the uterus is not too large, and B-ultrasound can be used to clearly observe the condition of the appendages. If there are ovarian cysts, fallopian tube masses, etc., they can be discovered and treated symptomatically in time. After this period, the uterus becomes significantly larger and the mass may be obscured and difficult to detect. In addition, you can also learn about the quality of the embryo from the B-ultrasound results, such as whether the gestational sac is good or not, whether it is an empty sac pregnancy, etc.

To sum up, this is an introduction to the question of what conditions are required for B-ultrasound examination of early pregnancy. After reading the above content, it should be of great help. I believe that there are many things that need to be understood during pregnancy, so as to ensure the best care for the pregnant woman and the fetus during pregnancy.
