• At 12 weeks of gestational age, an "average" nuchal thickness of 2.18mm has been observed; however, up to 13% of chromosomally normal fetuses present with a nuchal translucency of greater than 2.5mm.
  • At 12 weeks of gestational age, an "average" nuchal thickness of 2.18mm has been observed; however, up to 13% of chromosomally normal fetuses present with a nuchal translucency of greater than 2.5mm. Thus for even greater accuracy of predicting risks, the outcome of the nuchal scan may be combined with the results of simultaneous maternal blood ...
  • There was sort of a 1 in whatever chance. And they put in [partner's] age and it went from - my recollection is a bit hazy now because it was a long time ago - but it went from being something like 1 in 400 to 1 in 60, in seconds, like that, because of the enlarged nuchal fold. And we were just at that point quite devastated by it.
  • RESULTS: Nuchal fold thickness increased with GA in a linear manner from 3.13 ± 0.68 mm (mean ± SD) at 16 weeks to 5.08 ± 0.76 mm at 24 weeks. The 95th percentile measurement at 24 weeks remained less than 6 mm. CONCLUSIONS: A threshold of 6 mm appears to be appropriate for the diagnosis of a thick nuchal fold even for gestations between 20 ...
  • The nuchal translucency test, often called as the NT test ultrasound, refers to the collection of fluid under the skin at the back of the baby’s neck. It is the amount of this fluid that Nuchal translucency scan aims to measure. This scan is usually carried out between 11 – 14 weeks into the pregnancy, but is not very useful after the 14th ...
  • The Factors Assessed at the 1st Trimester Nt Scan are summarised as. Age of the mother; Amount of fluid behind the neck of the fetus (nuchal translucency) Presence or absence of the fetal nasal bone

Introduction. Effective screening for trisomy 21 is provided by assessment of a combination of maternal age, fetal nuchal translucency (NT) thickness, and maternal serum free beta‐human chorionic gonadotropin (β‐hCG) and pregnancy‐associated plasma protein‐A (PAPP‐A) at 11 to 13 + 6 weeks of gestation 1, 2. weeks. This combined with maternal age is thought to have a detection rate of approximately 95% for Down syndrome and trisomies 13 & 18. The false positive rate is about 5-7%. For your information, a nuchal translucency sonogram performed without maternal hCG and PAPP-
is considered to have an increased nuchal translucency, which is a marker for fetal aneuploidy, genetic syndromes, structural anomalies, and intrauterine demise [1]. Fetal nuchal translucency increases with crown-rump length, so gestational age must be taken into account when determining whether a given nuchal translucency thickness is increased.
Apr 17, 2012 · Hi all, I just had my NT scan @ 13 weeks. The combined result (scan + blood test @10 weeks) concluded that I have almost 1% (1 out of 95 chance) of having a down syndrome baby. The following are ... Age 40 Test done at 12w 0d Twin 1 hCG: 2.3717 MoM PAPP-A: 1.1570 MoM Nuchal fold: 2.1 Nasal bone present Tricuspid regurgitation Risk of trisomy 21: 1:26 Risk of trisomy 13/18: 1:2452 CVS confirmed no chromosomal abnormalities Twin 2 hCG: 2.3717 MoM PAPP-A: 1.1570 MoM Nuchal fold: 2.0 Nasal bone absent Tricuspid regurgitation Risk of trisomy 21 ...
This application allows estimation of risks for trisomies 21, 18 and 13 at 11-13 weeks' gestation by a combination of maternal age, fetal nuchal translucency thickness, fetal heart rate and maternal serum free ß-hCG and PAPP-A.Objective: To examine how women use the nuchal translucency (NT) risk adjustment in decision-making for invasive prenatal diagnosis. Study Design: Retrospective cohort study of 1083 consecutive NT screening exams. A screen-positive test was defined as a risk ≥1/300.
