The purpose of this study is to explore the application efficiency of BI-RADS grading standard in breast cancer screening, and to evaluate the impact of standardized training and quality control system on diagnostic quality by comparing the diagnostic consistency of doctors with senior professional titles (associate chief physician and above) and non senior professional titles (attending physician and below). Objective To explore the application efficiency of breast high-frequency ultrasound combined with BI-RADS grading in breast cancer screening, analyze the diagnostic consistency of doctors with senior professional title (associate chief physician and above) and non senior professional title (attending physician and below), and evaluate the application value of standardized training and quality control system. Methods Retrospective analysis of breast ultrasound cases in hospitals from January 2023 to June 2024 included 452 patients with suspected breast cancer. BI-RADS grading diagnosis was independently completed by 3 doctors with senior professional titles and 5 doctors with non senior professional titles. Kappa consistency test and chi square test were used for data analysis, and the results showed that there was no significant difference in the consistency of diagnostic results between the two groups of physicians (Kappa=0.86 vs 0.82, P=0.12), (P>0.05). Conclusion Standardized training and dynamic quality control can reduce the diagnostic difference of doctors with different professional titles. BI-RADS grading combined with high-frequency ultrasound has a high efficacy in screening breast cancer.
