Abstract: Objective To explore the value of case-based learning rounds(CBL) with application of PACS in the training of diagnostic capacity of radiology clinicians. Methods Peking University third hospital radiology department carried out the CBL rounds with application of PACS for 41 CT training clinicians in 2018, then compared with 39 CT training clinicians (without CBL rounds) in 2017. Ten reports written by each clinician(reported during the last training monthes) were randomly inspected from the PACS report system before and after the CBL rounds.These reports were scored, the excellent and good rate was calculated. The scoring criteria include accurate description of lesion imaging features, standardized report content, reasonable diagnosis logic, answering questions from clinical application form, making reasonable suggestions for further diagnosis and treatment, and no missed diagnosis. At the same time, questionnaires were used to evaluate the subjective feelings of training clinicians for CBL rounds, including comprehensive understanding of diseases, improvement of clinical analysis ability, reading images ability, and learning interest, and help of PACS for learning, expressed by percentage. Results 1)After CBL teaching, the report quality scores of clinicians increased(P＜0.01). 2)Satisfaction rate of clinicians was 90.2%,68.3%,80.5%, 75.6% and 80.5% respectively. Conclusions CBL rounds with application of PACS system is an effective method to train the diagnosis capacity of radiology clinicians.
