Technical Aspects of Nuchal Translucency Measurement

Seminars in Perinatology, 2005
Nuchal translucency (NT) describes an echo-free area, below the skin, in the posterior nuchal and back region of the fetus and is typically observed in the first and early second trimester of pregnancy. A wide NT has been correlated with chromosomal and congenital abnormalities in the fetus.

Intra‐ and interoperator repeatability of the nuchal translucency measurement

Ultrasound in Obstetrics & Gynecology, 2000
AbstractObjectiveThe aim of this study was to assess the repeatability of nuchal translucency measurement by well‐trained sonographers either experienced or inexperienced with the measurement.MethodsThe nuchal translucency was measured three times by two out of nine operators in 161 pregnant women attending two teaching hospitals.

Semi‐automated system for measurement of nuchal translucency thickness

Ultrasound in Obstetrics & Gynecology, 2010
AbstractObjectiveTo estimate intersonographer and intrasonographer variance components of fetal nuchal translucency (NT) thickness measurement using the traditional manual approach and a new semi‐automated system.MethodsA semi‐automated method was developed for measurement of the NT.

The effect of image size on nuchal translucency measurement

Prenatal Diagnosis, 2003
AbstractObjectivesTo assess the effect of altering image size on the absolute nuchal translucency (NT) measurement.MethodsNT was measured at three image magnifications (60%, 100% and 200%) in 120 singleton pregnancies.ResultsThe mean ± SD NT measurements were 1.52 ± 0.57 mm, 1.35 ± 0.53 mm and 1.18 ± 0.48 mm at 60%, 100% and 200% magnification ...

Three-dimensional transvaginal ultrasound improves measurement of nuchal translucency

Journal of Perinatal Medicine, 1999
The aim of the study was to correlate intra-observer reproducibility of the nuchal translucency measurements by two-dimensional and three-dimensional transvaginal ultrasound. Examinations were performed on 120 women undergoing ultrasound screening at 10 to 14 weeks' gestation.

Optimal crown–rump length for measuring the nuchal translucency

Journal of Clinical Ultrasound, 2007
AbstractPurpose.To determine the optimal crown–rump length (CRL) for obtaining nuchal translucency (NT) measurements.Methods.Women undergoing NT measurements by NT‐certified sonographers within a combined screening program over an 18‐month period were included in the study if they had a living fetus with a CRL of 45–84 mm.

Nuchal translucency measurement in fetuses with spinal muscular atrophy

Prenatal Diagnosis, 2011
AbstractObjectiveSpinal 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

Practice Tips for Measuring the Nuchal Translucency

Ultrasound, 2008
In some countries, measurement of nuchal translucency (NT) is incorporated into national antenatal screening programmes to help detect pregnancies at increased risk of Down syndrome. Accurate measurement of the NT requires a specific technique. This article is an illustrated practical guide outlining the steps required for measuring the NT; it ...

[Nuchal translucency: technical measurement and value].

Journal de radiologie, 2003
Nuchal translucency measurement is a very powerful screening test to detect chromosomal anomalies or other malformations. The technique for measurement is based on strict guidelines that will be described in this paper. Training is mandatory. Risk calculation for chromosomal anomalies (trisomy 21) must also consider maternal age and gestational age. In

Comparison and Reproducibility of Nuchal Translucency Measurements Using Two-Dimensional and Volume Nuchal Translucency Ultrasound: A Prospective Study

Fetal Diagnosis and Therapy, 2013
<b><i>Objective:</i></b> To assess the reproducibility and feasibility of automated nuchal translucency (NT) measurement (Volume NT©) in comparison to the two-dimensional (2D) manual approach. The Volume NT technique reveals the correct midsagittal plane automatically and measures the NT at the maximum distance with minimal ...
