Abstract Objective: To investigate the clinical value of ultrasound breast imaging reporting and data system(BI-RADS) in diagnosis of breast small carcinoma. Methods: We retrospectively analyzed ultrasound features, BI-RADS classification and pathological results of 255 small breast lesions which were diagnosed as 3~5 staged ultrasound BI-RADS. Results: The pathological results suggested that among 255 small breast lesions there are 191 benign lesions and 64 malignant lesions. The sensitivity, specificity, accuracy, positive predictive value(PPV) and negative predictive value(NPV) of ultrasound BI-RADS classification were 89.06%, 80.63%, 82.75%, 60.64% and 95.65%, respectively. The differences in non-circumscribed margin, irregular shape, aspect ratio>1, microcalcification in mass, lesions internal resistance index(RI)≥0.7, shadowing and the changes of surrounding tissue between benign and malignant lesions were statistically significant(P<0.05). Higher sensitivity was found in non-circumscribed margin(82.81%) and irregular shape(85.94%). Higher specificity was found in aspect ratio>1(89.53%), microcalcification in mass(90.05%), lesions internal RI≥0.7(92.67%), shadowing(95.29%) and the changes of surrounding tissue(99.48%). Conclusion: Ultrasound BI-RADS is of great value in diagnosing the benign and malignant breast masses and contributed to early detection, diagnosis, treatment of breast tiny carcinoma.
