One of the most widespread and informative ways of prenatal diagnostics is ultrasonography of a fruit. Ultrasonography allows to detect pathological conditions, the possible diseases of the child. Such diagnostics during pregnancy is traditionally carried out three times. Ultrasonography allows to estimate development of a fruit and also feature of a course of pregnancy. As physicians say, diagnostics method by means of BONDS waves is safe both for the kid, and for mom.
Triple ultrasonography is recommended to one and all future mothers. But in some cases ultrasonography diagnostics can be appointed in addition to make a full picture about the course of pregnancy. BONDS waves do not do any harm to the child and woman, and the myth about insecurity of prenatal diagnostics of a such type appeared because many confuse ultrasonography with X-ray.
For what ultrasonography is carried out
For performing ultrasonography the periods 11-13, 21-24, 32-34 weeks are considered as optimum terms. Pregnancy terms at the same time pay off proceeding from the first day of the last monthly. Each ultrasonography aims, but doctors do not appoint diagnostics in bigger volume because these researches usually do not bear any additional information on a condition of a fruit.
For the first time ultrasonography is carried out to detect possible genetic disorders, to establish the exact term of pregnancy, polycarpous pregnancy. The research allows to reveal the majority of heavy defects – hearts, chromosomal pathology and others. The second control ultrasonography will also help to find possible defects with late manifestation, to estimate a fruit condition whether there are no delays in development. Diagnostics in the second trimester of pregnancy is directed to fixing of degree of development of a placenta, condition of amniotic waters. The second ultrasonography allows to know a sex of the child. The third ultrasonography research is necessary to define extent of development of the kid, his situation in mom's womb, presentation. The doctor will estimate a condition of a placenta, amniotic waters and an umbilical cord.
Ultrasonography at pregnancy – it is safe
The harmlessness of ultrasonography diagnostics during pregnancy is proved by numerous researches. Inspection in the V-mode or standard can only disturb slightly the kid in mother's womb, but no more. Though there are no data that ultrasonography is capable to have negative effect on development of the child today, doctors seek not to appoint additional diagnostics needlessly. Duration of a research varies from several minutes to an hour, time increases if the uncomfortable position of the kid influencing to assessment of development of pregnancy and a fruit is recorded. There are also three- and four-dimensional ultrasonographies which give an opportunity to take pictures of the baby in a womb. Volume ultrasonography is carried out and to receive a cut of internals of your successor.
