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 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 کاملMeasurement of Nuchal Translucency Thickness for Detection of Chromosomal Abnormalities using First Trimester Ultrasound Fetal Images
The Nuchal Translucency thickness measurement is made to identify the Down Syndrome in screening first trimester fetus and presented in this paper. The mean shift analysis and canny operators are utilized for segmenting the nuchal translucency region and the exact thickness has been estimated using Blob analysis. It is observed from the results that the fetus in the 14th week of Gestation is ex...

متن کاملSimplified protocol of nuchal translucency measurement: Is it still effective?
OBJECTIVE Nuchal translucency (NT) is the most powerful screening tool for Down syndrome and congenital cardiac anomaly, therefore strict guidelines were established to get accurate NT values. However, to stick to the guideline in all pregnant women is time-consuming and superfluous in majority of low risk population. We undertook this study to investigate whether the simplified protocol enable...
