Une auto-évaluation simplifiée des images échographiques du premier trimestre

Conclusions Le score simplifié à quatre critères le plus performant comprend le plan sagittal de la CN, la position des calipers de la CN, l’agrandissement de l’image de CN et la qualité de la LCC. Ce score pourrait être le plus pertinent en pratique clinique dans le cadre du dépistage au premier trimestre. Objectives The objective of this study was to establish a minimum subset of simple criteria for the self-assessment of the quality of first-trimester ultrasound images of nuchal translucency (NT) and crown-rump length (CRL). Methods We designed 162 simplified image-scoring methods (ISM) based on 1, 2, 3 or 4 binary criteria derived from the 8 criteria of the original image scoring method of the French College of Fetal Ultrasound (CFEF). These ISM were assessed on 68,250 consecutive scans of the French national audit conducted by the CFEF on NT and CRL images. The ISM associated with the best precision to identify excellent/reasonable quality scans were selected. Results Simplified ISM based on 1, 2, 3 and 4 criteria showed maximum positive predictive values of 95.3% (95.11–95.50) 98.0% (97.87–98.14), 99.3% (99.17–99.35) and 99.7% (99.68–99.79), respectively, to identify excellent/reasonable quality scans. The proportion of excellent/reasonable scans was 2.8 to 16.7% when three criteria among the 8 were insufficient, and 0.17 to 3.95% when four criteria were insufficient. Conclusions The best performing ISM was based on the following four...
