Abstract
Objective To explore the application value of breast imaging reporting and data system (BI-RADS) in the diagnosis of mammography of Chinese female. Methods The clinical data of 1 551 women with mammography from September 2013 to February 2014 in the hospital were collected ,the results of histopathology as golden standard ,the classification of BI-RADS and pathological results were compared to calculate the sensitivity,specificity,positive predictive value(PPV) and the nega-tive predictive value (NPV). Results The 1 551 women with mammography were classified by BI-RADS:gradeⅠ,604 cases;gradeⅡ,1 287 cases;gradeⅢ,421 cases;gradeⅣ,112 cases;and gradeⅤ,57 case. 635 cases were treated by operation or biopsy,including 111 cases of malignant lesions and 524 cases of benign lesions. The sensitivity and specificity of BI-RADS were 82.9%(92/111) and 81.5%(427/524) respectively. The overall PPV of BI-RADS was 64.3%(92/143),and the overall PPV of gradeⅣandⅤwere 46.7%(43/92) and 96.1%(49/51) respectively,while the overall PPV of gradeⅡandⅢNPV were 97.2%(103/106) and 95.6%(324/339) respectively. Conclusion BI-RADS standardize the report with higher PPV and NPV,and it has important value in the diagnosis of benign and malignant breast lesions.关键词
