Analysis of Quality of Nuchal Translucency Measurements
Objective: Quantitative analysis of the quality of nuchal translucency (NT) measurements. Methods: This is a retrospective single-center study. NT was measured according to the Fetal Medicine Foundation (FMF) criteria by 20 trained obstetricians (October 2003-November 2009). The performance of NT measurements was analyzed with regard to several quality control standards. Accuracy according to e...
متن کاملAutomatic Nuchal Translucency Measurement from Ultrasonography
This paper proposes a fully automatic approach for computing Nuchal Translucency (NT) measurement in an ultrasound scans of the mid-sagittal plane of a fetal head. This is an improvement upon current NT measurement methods which require manual placement of NT measurement points or user-guidance in semi-automatic segmentation of the NT region. The algorithm starts by finding the pose of the feta...
متن کاملDistribution of nuchal translucency in antenatal screening for Down's syndrome
OBJECTIVE To determine whether the standard deviation of nuchal translucency (NT) measurements has decreased over time and if so to revise the estimate and assess the effect of revising the estimate of the standard deviation on the performance of antenatal screening for Down's syndrome. SETTING Data from a routine antenatal screening programme for Down's syndrome comprising 106 affected and 2...
متن کاملNuchal translucency measurement in first trimester Down syndrome screening.
(1) Approximately three in every four fetuses with Down syndrome have increased nuchal translucency (NT), which is a larger than normal build-up of fluid at the back of the neck. (2) The ultrasound measurement of NT between 11 and 14 weeks' gestation, in combination with the mother's age and the levels of placental biochemical markers in her blood, can be used to detect approximately 84% of fet...
متن کاملNuchal translucency and gestational age.
Professor Wald and his team (Wald et al., 2004) have remodelled the already modelled SURUSS data (Wald et al., 2003a) to claim, firstly, that their results are now similar to those of the multicentre study co-ordinated by the Fetal Medicine Foundation (Snijders et al., 1998), and, secondly, that the gestation of choice for nuchal translucency (NT) measurement is 10 weeks. The latest modelling e...
