The effect of nuchal cord on nuchal translucency measurement at 10–14 weeks

Ultrasound in Obstetrics & Gynecology, 1998
AbstractThe aim of this study was to determine the incidence of nuchal cord and its possible effect on nuchal translucency thickness at 10–14 weeks' gestation. Out of 316 consecutive pregnancies in which nuchal translucency thickness was measured transabdominally, 26 (8.23%) fetuses were shown to have the umbilical cord around the neck.

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.

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.

The effect of fetal neck position on nuchal translucency measurement

BJOG: An International Journal of Obstetrics & Gynaecology, 1998
Objective To determine the influence of the position of the fetal neck on nuchal translucency measurement.Design A prospective cross‐sectional study.Population One hundred and ninety‐six.Methods Nuchal translucency was measured in the mid‐sagittal plane, with the fetal neck in the flexed, neutral and extended positions ...

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

Measurement of Nuchal Translucency and the Prenatal Diagnosis of Down Syndrome

Obstetrics & Gynecology, 2009
To estimate the sensitivity of nuchal-translucency measurement and compare it with that of second-trimester serum screening using population-based data and to evaluate the effect of nuchal-translucency measurement on the gestational age at prenatal diagnosis of Down syndrome and pregnancy termination.We used The Paris Registry of Congenital ...

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 ...

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 ...

Nuchal Translucency Measurements for First-Trimester Screening: The ‘Price’ of Inaccuracy

Fetal Diagnosis and Therapy, 2007
<i>Objective:</i> First-trimester aneuploidy screening is in transition from the phase of ‘development’ to that of ‘diffusion.’ As with all other technologies, there is risk of diminished performance until newer centers are well experienced.

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.
