Use of NT ultrasound
Perhaps you have asked yourself what is the use of NT ultrasound? This ultrasound, which is in the field of screening ultrasounds, helps parents to be informed of the possibility of Down syndrome in their child and, in the event of such a thing, to obtain permission for a medical abortion. In other words, this method can help to have a society with healthy people and generations.
During this screening test, which is performed in the eleventh to fourteenth week of pregnancy, the expert doctor examines the different sizes and dimensions of the fetus, as well as the possibility of him having Down syndrome and a number of other chromosomal abnormalities and congenital heart disorders. With this advanced technology, many of his possible chromosomal disorders are checked before the fetus reaches four months of age.
To whom NT ultrasound is recommended?
This test is recommended for all pregnant mothers, but women over 35 years old and pregnant mothers who have previously given birth to a child with an abnormality or have people with a genetic abnormality in their family and first degree relatives must do this ultrasound test. Of course, you should know that the accuracy of this ultrasound in diagnosis is about 75%, and if it is combined with a blood test in real time and on the same day, this accuracy rate increases to 85%.In the mother's blood test, the level of hormones in her body is measured and checked, and the possibility of the fetus suffering from some genetic abnormalities such as Down syndrome, trisomy 13 and trisomy 18 is monitored. Trisomy means having three chromosomes instead of two normal chromosomes.

Remember that sometimes, even though the fetus has no problems, the NT ultrasound results indicate the high probability of some problems, which is called a false positive result. Sometimes it is possible that the opposite situation occurs and the results do not show a problem, while the fetus is facing a problem, which is called a false negative result. All these double the need for mothers to refer to a specialized and professional pregnancy screening center, which is one of the few and few such centers. This screening test requires the doctor's experience and expertise, and it is not the ultrasound machine, but his sharp look that illuminates everything well.Reasons for disturbing the result of nt ultrasound
Sometimes factors may cause disorders as a result of ultrasound;
- Overweight and excessive obesity of pregnant women
- Existence of feces in the intestines
- Abnormal low volume of amniotic fluid
- lying down badly during screening
- Placing the fetus in certain positions that make it difficult to see him
- more activity than the fetus
Some pregnant women ask if NT ultrasound is harmful? The answer to this question is absolutely negative because doing this ultrasound is absolutely good and necessary for the mother and the child on its way. In addition to diagnosing congenital and genetic abnormalities, this test also determines the exact age of the fetus and the relatively accurate time of normal delivery, although everything may change in the last weeks of delivery for some reasons. It should be remembered that during NT ultrasound, the nasal bone of the fetus is also examined, and its presence or absence can be recorded, because in congenital anomalies such as Down syndrome, the nasal bone blade is not formed in the fetus.
