Research suggests that by looking at the fetal face to see if the nasal bone is present or absent, in combination with the nuchal translucency (also spelled nucal translucency ) measurement, Further testing is usually offered if the recalculated risk after nuchal translucency measurement is greater than 1:300...

The main measurement (the actual nuchal translucency measurement) should be under 3.0 millimeters. My measurement was 3.3 millimeters (that's 3/10 of a...

BACKGROUND: Nuchal translucency (NT) measurement for Down's syndrome screening or detecting various fetal anomalies is a reliable sonographic marker. This study evaluates the contribution of NT screening in spontaneously conceived and assisted conception twin pregnancies.

Nuchal translucency (NT) measurement for screening chromosomal abnormalities and detecting fetal anomalies is an effective ultrasonographic marker, originally developed for singleton pregnancies. This study sought to evaluate the feasibility of NT measurements in higher order multiple gestations.

Earlier parameters used included the actual to expected FL ratio, the BPD/FL ratio. More recently the nuchal translucency thickness is used in detecting Down syndrome fetuses. In the measurement of the nuchal skin fold thickness, critical landmarks should include the cavum septum pellucidum, the cerebral peduncles and...

Conclusions: Measurement of fetal nuchal translucency thickness traditionally used to identify fetuses at high risk of aneuploidy at 10-14 weeks of gestation can identify a large proportion of fetuses with major defects of the heart and great arteries.

Several groups have demonstrated an association between an increased nuchal translucency and aneuploidy, particularly Down syndrome. There are many studies that have shown that nuchal translucency measurement can be used as a screening test for Down syndrome between 10-14 weeks gestation.
