A nuchal translucency (NT) scan can help determine how likely it is that the fetus has a congenital or genetic condition. If you have an irregular result, don’t panic. NT tests are screenings, and abnormal tests mean more tests are needed.

Nuchal translucency (NT) is the sonographic appearance of a collection of fluid under the skin behind the fetal neck in the first-trimester of pregnancy. The term translucency is used, irrespective of whether it is septated or not and whether …

2025年2月17日 · Fetuses with nuchal translucency between 3.0 and 3.4 mm have high rates of chromosomal aberrations, highlighting the importance of prenatal screening. Our findings support proposing routine invasive testing for fetuses with nuchal translucency between 3.0 and 3.4 mm.

2025年1月17日 · Nuchal translucency is the normal fluid-filled subcutaneous space identified at the back of the fetal neck during the late first trimester and early second trimester (11 weeks 3 days to 13 weeks 6 days).

Subjects 17 446 pregnancies, from which chorionic villous samples had been taken after assessment of risk for trisomy 21 by measurement of fetal nuchal translucency (NT) thickness at 11 to 13 +6 weeks of gestation. Interventions Analysis of chorionic villous samples by full karyotyping and by qf-PCR for chromosomes 13, 18, 21, X, and Y.

First trimester screening (FTS), nuchal translucency (NT) and noninvasive prenatal testing (NIPT) are prenatal tests that provide information on a developing baby’s risk for certain genetic anomalies.

Based on ultrasonography, the associations of increased NT fetuses are described in relation with Down syndrome, Cardiac anomalies, and a diverse range of other anomalies.

Fetal nuchal translucency can be measured in most pregnant women in the first and early second trimester. The size of translucency varies slightly with gestational age and crown rump length and is independent of maternal age.

A nuchal scan or nuchal translucency (NT) scan/procedure is a sonographic prenatal screening scan to detect chromosomal abnormalities in a fetus, though altered extracellular matrix composition and limited lymphatic drainage can also be detected.
