2D Ultrasound: This is the most important fetal examination procedure, and the following modalities - 3D, 4D and 5D - illustrate this. Let's take a look at when and what role these important filters have.It is important to know that the three-dimensional ultrasound scan only serves to supplement the two-dimensional images. This is because images in 2D dimensions are best suited to the fact that ultrasound professionals can reliably exclude and eliminate the majority of developmental abnormalities that may be present in the fetus. A 4-dimensional procedure can help a lot, such as lip splits. 3D and 4D images represent the fetus in space, 3D image is a flash image, while 4D image is a real-time image of the fetus. The 5-dimensional examination is a new procedure, and parents can view 3-D images and 4-dimensional images made during the examination on a picture-capable TV with the help of a special eyewear. Like all examinations, ultrasound has its conditions. Transformation of engraving images in three dimensions is not always possible, and the quality of the images and videos depends heavily on the pregnancy, the position of the fetus and the body of the mother.
Ultrasound is completely safe for the fetus
When? What?The first pregnancy test is shown in Figures 6-8. weekly, ultrasound examination of the menstrual period can be used to determine pregnancy, excess pregnancy, and the position of the embryo inside or outside the uterus. 12-13. during the first week of pregnancy, the first genetic ultrasound test to determine the exact age of the pregnancy, : FL, croup distance: CRL, presence of nasal bone: NB and thickness of the occiput: NT). The latter two values are important because some chromosomal abnormalities may have values that are different from the normal. Such a disease is, for example, the Down disease. Thickness up to 3 mm is normal, but this does not mean that fetuses with NT values above 3.0 mm are unequivocally ill. The measured values depend on many things (eg the age of the fetus is influenced), but of course the specialist gives information. Nasal deficiency can also be a sign of chromosomal abnormalities, for example, in a large proportion of Down's fetuses, the nasal bone is shown to be deficient or very small (hypoplasia).
18-20. the second genetic ultrasound is being conducted weekly. This is when the signs of developmental chromosome abnormalities (minor marks) are detected, and the open spine and skull developmental abnormalities are filtered. With a good quality ultrasound device, the open spine can be filtered at least 95, and the skull defect can be filtered at 100 percent. Within the framework of genetic ultrasound, a thorough examination of the internal organs of the fetus is carried out, with fetal focal ultrasound of particular importance, as heart development disorders are often associated with certain chromosomal abnormalities. Pregnancy 30-31. weekly ultrasound scans, fetal biometrics, localization and degree of maturation of the fetus, and amniotic fluid volume can be observed.
The last ultrasound examination is pregnancy 36-37. week for monitoring fetal growth, positioning, placental status, and birth control planning.
Did the baby care?The principle is that the fetus should always be examined for as long as necessary for the practitioner to gather all the necessary information. If you are certain that there is no abnormality, the examination should be completed. The reason is that long-term ultrasound also has physical effects: ultrasound waves are absorbed by cells, which can cause the tissues to warm up. Although the safety of ultrasound examinations has been proven by countless prior scientific examinations, we are not aware of any maladministration at this time, however, no precaution should be taken.
