Analysis of Quality of Nuchal Translucency Measurements

Donald School Journal of Ultrasound in Obstetrics and Gynecology, 2011
ABSTRACT 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).

Deep Learning Measurement Model to Segment the Nuchal Translucency Region for the Early Identification of Down Syndrome

Measurement Science Review, 2022
Down syndrome (DS) or Trisomy 21 is a genetic disorder that causes intellectual and mental disability in fetuses. The most essential marker for detecting DS during the first trimester of pregnancy is nuchal translucency (NT).
