Each thyroid nodule was evaluated using three methods: conventional ultrasound for C-TIRADS scoring, shear wave elastography (SWE), and AI-assisted diagnosis. The diagnostic performance of individual methods and their combinations was assessed within each nodule size group using sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve. For combined assessments, a nodule was considered positive if any constituent method indicated malignancy. Intergroup comparisons of AUC values were performed using DeLong\u2019s test to evaluate the effect of nodule size on diagnostic performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In nodules \u22651 cm, AI demonstrated excellent performance (AUC = 0.875, sensitivity = 96.43%, specificity = 77.78%), and C-TIRADS also performed well (AUC = 0.834, sensitivity = 96.55%, specificity = 70.37%). Among SWE parameters, Emax achieved the highest AUC (0.895). The diagnostic efficacy of AI combined with C-TIRADS (AUC = 0.852) was comparable to that of AI + C-TIRADS + Emax. In subcentimeter nodules, diagnostic performance decreased, with AI achieving an AUC of 0.654 and C-TIRADS an AUC of 0.524, whereas Emean retained moderate discriminative ability (AUC = 0.821).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>AI combined with C-TIRADS provides an efficient and practical strategy for diagnosing thyroid nodules \u22651 cm.
