For any future mother, you must be sure that her baby is developing correctly, without different deviations and violations. Therefore, after the first ultrasound examination, a pregnant woman learns about such a thing as fetometry of the fetus by weeks. Thanks to this type of ultrasound examination, you can find out the sizes of the parts of the fetal body, verify the correctness of the pregnancy period set by the doctors and see possible deviations in the dynamics of the baby’s development.
The main task of fetal fetometry
1. Doctors and the expectant mother after this method of research will be able to verify the proper level of development of the fetus, for example, to specify the size of the fetus, which 5 weeks.
2. After 20 weeks, you can clarify the gender of the unborn baby.
3. Thanks to the first ultrasound, you can see the "first smile" of your baby and record his movement.
Description of the main indicators of diagnosis
Fetometry of the fetus by weeks allows specialists to verify the correct development of the child. The first ultrasound examination has the following indicators:- KTR (coccygeo-parietal size) is characteristic for short gestation, when the fetus has not yet reached sizes of 20-60 mm.
- BDP (biparietal size) - this indicator is associated with the second trimester of pregnancy and provides an opportunity to know its term with an accuracy of 10 days.

Fetometry of the fetus by weeks is really of great importance for doctors and parents of the unborn baby. But not everyone will be able to independently understand the conclusion of specialists in the absence of a special higher medical education.In order to find out the estimated number of births of your baby, you should pay attention to the obstetric period of pregnancy. This date is easily calculated thanks to information about the first day of the last menstrual cycle. At the same time, it is imperative to take into account those indicators that were obtained after fetometry. Although in this case, different interpretations of the same indicator are possible.
The simplest algorithm for reading the conclusion of ultrasound
1. Thanks to the knowledge of the first day of the last menstruation or the day of conception, it is possible to calculate the approximate date of birth of the baby.2. ( ) 1 2 .

In order to find out the preliminary date of birth of your long-awaited child, it is necessary to calculate the available data using the Negele formula. So, you need to add a week to the date of the last menstruation, and then take three months.
But nevertheless, in order to verify the accuracy of such calculations, it is necessary to take into account the results of ultrasound examination. Although, even in this case, errors are possible. Because the diagnostic equipment of medical facilities may be inaccurate. So fetometry, the table of which is considered the main reference point in the process of ultrasound examination, is somewhat relative. After all, it also has its own variations.
In this case, do not worry very much. After all, the differences are insignificant and can not greatly affect the overall result., , , .

For example, all ultrasound indicators are normal, but the length of the thigh and tibia does not fit the normal value at all. Do not immediately panic and think that this pathology is necessarily developing. After all, all people are different, maybe your child’s legs are not as long as the norm indicates. Although everything is actually in order, and your baby is completely healthy.At the same time, it is important that the table of fetal sizes allows you to pay attention to the following: the danger in most cases is justified when, after the next study of fetometry, certain values differ by more than two lines. In other words, when the pattern is visible in the lag from the norm.

In most cases, the third fetometry is considered the last for the expectant mother. 33 weeks of gestation is the last term for an ultrasound scan. After all, it is now possible to see a fully formed baby, evaluate its state of health and judge the further method of childbirth. For example, the circumference of the head and abdomen is measured, the symmetric development of paired limbs is assessed, and the baby’s birth weight is also predicted.Moreover, if there is a need for this, it is possible to conduct a study earlier, such as fetometry. 32 weeks is considered a sufficient period for such a study of women in the situation. If pathologies and striking deviations from the norm are not detected, then in the future there is no need for an ultrasound examination.
