Analysis of Quality of Nuchal Translucency Measurements

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 20trained obstetricians (October 2003-November 2009). The performance of NT measurements was analyzed with regard to severalquality control standards. Accuracy according to experience, professional profile, crown-rump length (CRL) values and FMF certificationwas statistically tested.Results: A total of 14,978 NT measurements were assessed. (1) The mean operator-specific median NT-MoM values was 0.98. (2) Meanpercentage of cases >95th and 60 mm had a statistical impact improving thesestandards.Conclusion: Overall quality standards show optimal NT measurements in our unit. Experience a dedicated profile to fetal medicineultrasound, CRL over 60 mm and FMF certification has a significant positive impact on the quality standards.
