Normal value of nt on ultrasound examination

Generally, expectant mothers need to have their NT value checked around 10-15 weeks of pregnancy to judge the health of the fetus. If the test value is higher than the standard value, it indicates that the fetus may be deformed and further examination is required. So, how much is the normal range of NT value?

The NT value (neck translucency) refers to the thickness of the fluid accumulation in the subcutaneous tissue fluid behind the fetus's neck. When the neck translucency is greater than or equal to 2.5mm, it can be identified as thickening of the neck translucency. The degree of thickening of the neck translucency is closely related to fetal abnormalities. The more obvious the thickening of the nuchal translucency, the higher the chance of fetal abnormality and the more serious the degree of abnormality.

If repeated accurate measurements are higher than the standard value, then it is recommended that the expectant mother undergo amniocentesis to check the sex chromosomes. Check the Down's test to see if there are any abnormalities. To eliminate deformed fetuses. Most of the thickened NT will naturally disappear by 20 weeks of pregnancy. Generally, the NT value test is performed between 11 and 13 weeks of pregnancy. Generally speaking, ultrasound examination is more accurate. If the NT value is >0.3cm, amniocentesis is required to further rule out fetal malformations.

The NT value is an ultrasound measurement of the thickness of the nuchal translucency layer of the fetus at 10-14 weeks of pregnancy. Any value <2.5mm is considered normal, and any value greater than or equal to 2.5mm is diagnosed as thickening of the nuchal translucency layer. When the cyst thickens extremely, it may cause cystic hygroma in the fetal neck, which is a congenital disease.

Can NT value determine the gender of the baby?

Can NT value tell whether a man is a woman? Although there are many prenatal examinations that can tell the gender of the fetus, the NT test cannot. This is just a test to check the translucency of the fetus's neck. Through this test, it can be found out whether the fetus has any abnormalities, so that the mother can understand the condition of the fetus in time.

The NT check list cannot determine the sex of the fetus. NT is used to screen the nuchal translucency of the fetus. This is the initial test to determine whether the fetus has congenital neural tube defects.

The NT test is a test of the fetus's neck. It is commonly used in prenatal diagnosis and can diagnose chromosomal diseases at an early stage and detect fetal abnormalities caused by various reasons at an early stage. If it exceeds 3mm, it often indicates poor fetal outcome, which is usually checked with BC.

Basic obstetric B-ultrasound examinations mainly focus on the growth and general structure of the fetus. With the development and popularization of transvaginal ultrasound, more attention is paid to the proportion relationship between the various tissue structures of the fetus. Qualitative test indicators are used to predict whether the fetus has certain defects, especially chromosomal abnormalities. For example, measurement of the fetal nuchal translucency has become one of the effective methods for prenatal diagnosis of fetal chromosomal abnormalities.

Although the NT test uses B-ultrasound to observe the fetus's condition, the key to the NT test is to observe the thickness of the nuchal translucency. To determine the boy or girl, the doctor needs to use an ultrasonic device to take a picture of the fetus's sexual organs. Therefore, it is impossible to determine the sex of the fetus based on the NT test alone.
