What are the differences between NT, color ultrasound and B-ultrasound taken during pregnancy?
Pregnancy check-up is the most important thing for every pregnant mother, but there are too many prenatal check-up items during pregnancy, including NT, color ultrasound and B-ultrasound. Many pregnant mothers cannot distinguish between them. Today we will talk about them. The difference between these three!
1. NT
NT examination is mainly a scan of the translucency behind the fetal neck, which is a method used to evaluate whether the fetus may have malformations in early pregnancy
NT refers to a clear liquid that exists in the neck of the fetus. Generally speaking, NT only exists between the 11th and 14th weeks of the fetus.
After 14 weeks, the NT in the fetal neck will be absorbed by the lymphatic system in the fetal body, and the existence of NT cannot be observed through examination.
The purpose of the NT examination is to determine whether the fetus has Down syndrome or malformation based on the NT value in the test results. If the NT value is too high, the fetus may have these two conditions. disease.
2. Color Doppler Ultrasound
Color Doppler Ultrasound can clearly see the baby’s movements in the mother’s belly, and can also display the baby’s body organs and development to a certain extent. Therefore, the color ultrasound examination can see whether the child's development is normal?
It can also detect whether the child has limb deformities and internal organ malformations, and whether there are congenital diseases in the child.
Through color ultrasound examination, you can also check whether the fetus has spina bifida, cleft lip and brain hypoplasia.
So color ultrasound examination is mainly an examination to rule out congenital diseases and malformations of the fetus.
3. B-ultrasound
B-ultrasound is a very common ultrasonic examination method, which is generally used by doctors to assist doctors in examining various organs in the human body.
During a woman’s pregnancy, B-ultrasound is used to check the development of the fetus, the shape of the fetal organs, the condition of the amniotic fluid and the placenta, and three-dimensional or four-dimensional ultrasound technology is added to the B-ultrasound to check the fetus. Are there any deformities?
NT examination is also performed through B-ultrasound, and whether it is NT examination, color ultrasound, four-dimensional color ultrasound, or three-dimensional color ultrasound, all examinations are based on B-ultrasound.
So, NT examination is also carried out through B-ultrasound examination. Therefore, there is no difference in the examination methods between the two pregnancy test items, B-ultrasound examination and NT examination.
