How is the CTE of the fetus measured?

Today, every pregnant woman has the opportunity to bear a healthy fetus, since modern equipment allows you to diagnose not only the duration of pregnancy, but also to exclude the possibility of developing some abnormalities or pathologies in the development of a future child. So, by determining the age of the fetus, obstetricians carry out a large number of measurements and compare the results with the established values. The most accurate parameter determining the development of the future baby is the KTP of the fetus, that is, its coccygeal-parietal size. It is measured with the help of ultrasound, most often at a period of up to eleven weeks, since the accuracy of measurements decreases from the twelfth week. According to the KTR of the embryo, you can determine not only the duration of pregnancy, but also the size and approximate weight of the baby.

The special table shows the CTE values of the fetus for weeks, they are the average indicator of the norm, since small fluctuations in the development of the future child are permissible, which are not any deviations. This is especially true in the second trimester. Once again, we emphasize that the table allows a normal error of four days in calculating the gestational age. After sixteen weeks, the CTE of the fetus is not measured.

It is important here not only to correctly put the period of pregnancy, but also to monitor the development of the child. In case of significant abnormalities, it is necessary to consult a doctor and only with him to decipher the results.

If we consider the KTR table for weeks, it immediately strikes that after the eleventh week, the figures in it almost double. So, if earlier КТР increased by 1 mm, then after the twelfth week it will grow by almost 2 mm (per day).

The most optimal is the measurement of CTF of the fetus at the eleventh week, because early diagnosis makes it possible to identify developmental defects in their early stages, this allows them to be eliminated and pregnant with a healthy pregnancy.

Consider how the KTR is determined

To determine the CTE, scans are used in different planes, while the largest length of the embryo is determined by measuring from the cranial pole to the edge of the buttocks (the bile sack and limbs are not included here).

Thus, in the first trimester of pregnancy , using ultrasound, the diameter of the fetal egg and the coccyx-parietal fetal size is determined. These all measurements make it possible to accurately determine the duration of pregnancy, since in this period the size of the future baby is most closely approximated to the standards.

If you look at the table for measuring the CTE of the fetus, you can see that at six weeks it is seven millimeters, by the seventh week this figure has grown to ten millimeters, by the beginning of the eighth week - sixteen millimeters, on the ninth - twenty-three millimeters, the tenth week is characterized by indicators In thirty-one millimeters, and the eleventh - forty millimeters.

From the twelfth week of pregnancy, the CTE of the embryo will grow at a slightly higher rate, this week they are equated to fifty-two millimeters. The thirteenth week is characterized by a KTR of sixty-six millimeters.

Thus, the study of the CTE of the fetus plays an important role in the study of the course of a woman's pregnancy . Thanks to this indicator it is possible not only to determine the exact period of pregnancy, but also to reveal deviations in the development of the embryo at an early stage, which in turn increases the chances of their elimination and the production of a healthy child.

It should be noted that it is not recommended to determine the size of the fetus by the results of ultrasound alone, leave it to experienced experts, and then you will know about the real state of your future baby.
