Automatic 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 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 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 کاملNuchal translucency measurement in fetuses with spinal muscular atrophy.
OBJECTIVE Spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disorder with a high carrier frequency in the general population. The severity of this disorder indicates the importance of early prenatal detection. In medical literature, there are a few published case reports of enlarged nuchal translucency (NT) measurement in association with a diagnosis of SMA in the fetus....
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...
