There is no study on whether 1.1mm or 1.4mm of fetal nuchal translucency is better. Generally, fetal nuchal translucency is normal as long as it is less than 2.5mm, and there is no such thing as which is better.
Fetal nuchal translucency thickness is within the normal range, indicating that it is normal. It indicates that the risk of fetal chromosomal abnormality is low and there is usually no need to worry too much. Regular routine checkups need to be performed afterwards to find out the growth and development of the fetus.
However, if the fetal nuchal translucency thickness is greater than or equal to 2.5mm during the NT (Nuchal Translucency Thickness) examination, it is an abnormal condition, and prenatal diagnosis is needed to further clarify whether there is any abnormality in the fetus, including fetal chromosome abnormality syndromes, monogenic diseases, viral infections, congenital heart disease, and so on.
If any abnormality occurs, it is recommended to go to the hospital in time for examination and standardized treatment under the doctor’s advice.
