Abstract
This study evaluated the efficacy of a combined artificial intelligence (AI)-assisted and traditional teaching model in enhancing radiology residents' diagnostic competency for pulmonary nodules on chest Combined Teaching (CT). In this randomized controlled trial, 36 s-year residents were allocated to three groups: Traditional Teaching (TT), AI-Assisted Teaching (AI-AT), and CT. All received standardized theory instruction. TT underwent 2 h of mentored film-reading. AI-AT completed 2 h of AI platform training. CT received 1 h of AI training followed by 1 h of expert-led review of challenging cases. Assessments included theoretical and practical exams, diagnostic process metrics, and a 1-month follow-up survey on confidence, cognitive load, and AI perceptions. The CT group significantly outperformed both the TT and AI-AT groups in post-test theoretical (CT: 91.8 ± 3.4 vs. TT: 82.6 ± 3.2, P < 0.001; vs. AI-AT: 86.2 ± 2.9, P = 0.003) and practical scores (CT: 93.5 ± 2.7 vs. TT: 81.9 ± 3.0, P < 0.001; vs. AI-AT: 86.8 ± 3.0, P < 0.001). Analysis of diagnostic process metrics revealed the CT group engaged in more deliberate analysis (longer reading time, P = 0.01) and demonstrated superior completeness in describing key imaging features (P < 0.001). At the 1-month follow-up, the CT group maintained higher diagnostic confidence (P = 0.002) and exhibited a more balanced perception of AI as a collaborative tool. This exploratory randomized controlled trial demonstrates that the integration of AI-AT with traditional expert-led sessions is significantly more effective than either method alone in improving radiology residents' diagnostic performance and clinical reasoning for pulmonary nodules. This combined model fosters deeper cognitive engagement and sustainable learning outcomes, providing a framework for competency-based education in the AI era.
