Measurement of fetal nuchal translucency thickness by three-dimensional ultrasound.
OBJECTIVE To investigate the feasibility and repeatability of nuchal translucency thickness measurement using three-dimensional ultrasound. METHODS Forty consecutive women with uncomplicated singleton pregnancies attending for Down syndrome screening at 11-14 weeks' gestation were included in this prospective crossover trial. Nuchal translucency thickness was measured using both two-dimension...
متن کاملAnalysis 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 کاملSemi-automated system for measurement of nuchal translucency thickness.
OBJECTIVE To estimate intersonographer and intrasonographer variance components of fetal nuchal translucency (NT) thickness measurement using the traditional manual approach and a new semi-automated system. METHODS A semi-automated method was developed for measurement of the NT. In this method, the operator places an adjustable box over the relevant area at the back of the fetal neck. The sys...
متن کاملNuchal translucency: an ultrasound marker for fetal chromosomal abnormalities.
CONTEXT The literature shows an association between several ultrasound markers and chromosome abnormality. Among these, measurement of nuchal translucency has been indicated as a screening method for aneuploidy. The trisomy of chromosome 21 has been most evaluated. OBJECTIVE To define the best fixed cutoff point for nuchal translucency, with the assistance of the ROC curve, and its accuracy i...
