Abstract： Objective To improve ultrasound physicians’proficiency in Thyroid Imaging Reporting and Data System （TI-RADS） through the training mode combining cased-based learming （CBL） and PDCA cycle based on the rising detection rate of thyroid nodules and the suboptimal application of TI-RADS by ultrasound practitioners. Methods A training program，including TI-RADS theoretical lectures， stratified case reviews，pathology-based discussions，and clinical practice feedback，was conducted in the Ultrasound Department of Shaanxi Provincial People’s Hospital from September to November 2O23.Pre- and posttraining assessments included theoretical examinations，case interpretation accuracy，and clinical application metrics.Results A total of 5O ultrasound physicians completed the training.The accuracy of benign and malignant thyroid nodule differentiation improved significantly （57.6% vs. 63.3% ， P=0.003 ），and TIRADS 4a classification accuracy increased from 38.0% to 58.0% （ P<0.001 ）. The proportion of Category 4 and 4a nodules in ultrasound reports decreased markedly，while malignancy detection rates via contrastenhanced ultrasound 60.0% vs. 82.0% ， P<0.001 ）and fine-needle aspiration biopsy （80.0% vs. （2 90.0% ， P<0.001 ） rose substantially. Conclusion The training mode of CBL integrated with PDCA cycle effectively enhances ultrasound physicians’mastery of TI-RADS.
