Objective Screening for trisomy 21 by fetal nuchal translucency (NT) thickness at 11 to 13+ 6
weeks' gestation requires an appropriate examination of the NT. Errors in the assessment of …

Objective To estimate intersonographer and intrasonographer variance components of fetal
nuchal translucency (NT) thickness measurement using the traditional manual approach …

Objective To compare the intra‐and interoperator reliability of manual and semi‐automated
nuchal translucency thickness (NT) measurement by sonographers with different levels of …

Objective To evaluate the feasibility of Volume NTTM, a new technique that automatically
archives mid‐sagittal plane views and measures the maximum nuchal translucency (NT) …

Objectives To determine the effect of different ultrasound machine–probe combinations on
nuchal translucency (NT) measurements and to assess how this impacts on the accuracy of …

Objective To define the impact of nuchal cord on the measurement of fetal nuchal
translucency thickness (NT). Methods Between December 2004 and June 2006, we …

Objective To examine the effectiveness of screening for trisomy 21 by a combination of
maternal age and fetal nuchal translucency thickness at 10–14 weeks of gestation in …

Objective To investigate the feasibility and repeatability of nuchal translucency thickness
measurement using three‐dimensional ultrasound. Methods Forty consecutive women with …

Objective To develop a quantitative quality control process of nuchal translucency (NT)
measurement at 11–14 weeks of gestation based on the mixture model, characterized by …

Objective The variability of nuchal translucency thickness (NT) measurements in the first
trimester appears to be associated in part with caliper placement. Methods for obtaining …
