Abstract

Abstract: Objective To explore the learning curve of first-year residents with different educational backgrounds inmastering the 2017 American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS).Methods A total of 21 first -year residents who participated in standardized training for residents at Ultrasound Center ofFoshan First People's Hospital from 2023 to 2025 were selected. They were divided into a postgraduate group (8 residents)and an undergraduate group (13 residents) based on their educational backgrounds. After receiving training on ACR TIRADS, 125 thyroid cases were randomly divided into 5 groups with 25 cases each, which were distributed to the residentsfor assessment in 5 separate sessions. Taking the TI-RADS classification results of senior physicians as the referencestandard, each resident's classification results were compared with those of senior physicians: 4 points were awarded forconsistency and 0 points for inconsistency. Meanwhile, the time spent on each assessment was recorded, and learning curveswere plotted. Results The assessment scores of both groups showed an upward trend at all stages, with a statistically significant difference (F=14. 690, P＜0. 001). The scores of the postgraduate group increased significantly from the secondassessment and then stabilized. There was no statistically significant difference in the scores between the two groups acrossthe 5 assessments (F=3. 158, P=0. 092). Conclusion After theoretical training and reading 50 thyroid nodule cases, firstyear residents can basically master ACR TI-RADS classification and achieve stable performance, with postgraduate residentsdemonstrating better mastery.
