N2 - Objectives: To evaluate the effect of training radiology residents on breast ultrasonography (US) according to the Breast Imaging Reporting And Data System (BI-RADS) and the factors that influence the training effect. Methods: This multicenter, prospective study was approved by eight institutional review boards. From September 2013 to July 2014, 248 breast masses in 227 women were included for US image acquisition. Representative B-mode and video images of the breast masses were recorded, among which 54 cases were included in the education set and 66 in the test set. Sixty-one radiology residents scheduled for breast imaging training individually reviewed the test set, immediately before, 1 month after, and 6 months after training. Diagnostic performances and US descriptors of the residents were evaluated and compared against those of expert radiologists. Results: Agreements between residents and experienced radiologists showed improvement after training, while agreements between post-training and post-6-month training descriptors did not show significant differences (all p > 0.05, respectively). Sensitivity, negative predictive value (NPV), and AUC were significantly improved for residents post-training and post-6-month training (all p < 0.05), while approximating the performances of expert radiologists except for AUC (0.836, 0.840, and 0.908, respectively, p < 0.05). Low levels of pre-training AUC, total number of breast US examinations, and the number of sessions per week that residents were involved in were factors influencing the improvement of AUC. Conclusion: Training using education material dedicated for breast US imaging effectively improved the diagnostic performances of radiology residents and agreements with experienced radiologists on US BI-RADS features. Key Points: • Agreements on lesion descriptors between residents and experienced radiologists showed improvement after training, regardless of test point. • Sensitivity, NPV, and AUC were significantly improved for residents in post-training and post-6-month training (all p < 0.05). • Low levels of pre-training AUC, total number of breast US examinations, and the number of sessions per week that residents were involved in were factors influencing the improvement of AUC.
