“…A good quality ultrasound machine can help the sonographer to magnify the picture without losing the details and place the caliper precisely. To maintain quality in our study we used a standardized protocol for our measurements and continuously reviewed the images as suggested by the FASTER Trial [19]. NT measurements can be done either by TAS or TVS.…”

“…The measurement should be made between 11 and 14 weeks, with best performance obtained at 11-12 weeks (Malone et al, 2005b;Wright et al, 2008) when the measurement is performed by qualified ultrasonographers undergoing regular quality assessment (Evans et al, 2007;D'Alton et al, 2009). Of fetuses with NT above the 95th centile, about 20-30% have a chromosomal aberration Bilardo et al, 2007).…”

“…Dans l'étude multicentrique internationale First and Second Trimester Evaluation of Risk of Aneuploidy (FASTER) -destinée à comparer différentes stratégies de dépistages de la trisomie 21 -37 018 clichés ont été relus et neuf critères de qualité ont été recherchés. Au total, 96,9 % des clichés ont été jugés acceptables, mais la manière dont l'acceptabilité des clichés a été déterminée n'est pas précisée [15]. Dans l'étude Biochemistry Ultrasound Nuchal Translucency (BUN), l'évaluation des mesures de clarté nucale fut mixte (qualitative et quantitative).…”

“…C'est le seul pour lequel la cotation ne variait pas dans notre étude entre l'autoévaluation et la relecture. Les calipers étaient bien placés dans 86,0 % des clichés dans notre étude, dans 75,2 % des cas chez Herman, dans 53 % des cas dans l'étude BUN et dans 26,7 % des cas dans FASTER [7,14,15]. Cet item est lié au grossissement de l'image et à la visibilité de l'amnios.…”
