Abstract:
[Objective] The objective of this study was to evaluate the diagnostic accuracy of the 2013 edition of Breast Imaging Reporting and Data System (BI-RADS) ultrasound lexicon in diagnosing breast categories 3-5 lesions.[Methods] Using our breast ultrasound database from June 2014 to June 2016,we identified 4428 BI-RADS category 3 to 5 lesions with a known pathological diagnosis in 4 428 adult women.The positive predictive value (PPV) of each BI-RADS category was calculated based on the pathological diagnoses and compared with the reference range provided by the American College of Radiology (ACR).[Results] 4 428 lesions from 4428 patients were included in this study.The PPV of each BI-RADS category waswithin the reference range provided by the ACR in 2013.1198 (27.1％) pathological malignant/borderline results were found in the 4 428 lesions,the other 3 230 (72.9％)lesions were diagnosed with benign results.Among the malignant/borderline lesions,the rate of lymph node metastasis gradually increased as the BI-RADS categories were upgraded.Malignant lesions with a diagnosis ofinvasive ductal carcinoma or invasive lobular carcinoma showed an increasing distribution trend from category 3 to 5.[Conclusion] The 2013 editionof BI-RADS ultrasound lexiconhas good diagnostic accuracy and efficiencyin clinical practice.
