Abstract

Fetal nuchal translucency (NT) thickness was evaluated in 34 fetuses in the first trimester. This was a retrospective study using stored values of the head volume from normal fetuses at 11—14 weeks. Two experienced operators each measured the NT thickness, twice manually and twice using the semi-automated software. The intraoperator SD for manual measurements was 0,144 mm for Operator 1 and 0,162 mm for Operator 2, and for semi-automated measurements it was 0,034 mm for Operator 1 and 0.051 mm for Operator 2. NT thickness can be assessed reliably using the semi-automated algorithm, which allows standardization of the NT assessment process.
