Abstract:
0.05). A Kappa value was 0.435 for overall final assessment. There were moderate agreement in category Ⅰ and Ⅴ (K=0.511 and 0.671), and slight agreement in category Ⅱ (0.373), Ⅲ (0.179), and Ⅳ (0.276). The positive value of different categories assessed by two groups were as follows: category Ⅰ (12.5% vs 22.5%), Ⅱ(3.7% vs 12.5%), Ⅲ(20.83% vs 19.61%), Ⅳ(68.63% vs 60.34%), and Ⅴ(100% vs 89.91%). Twenty three lesions(7.49%)were misdiagnosed by both groups. Conclusion BI-RADS is useful in mammographic diagnoses of breast lesion with symptoms. The misdiagnoses can be reduced combined with the clinical examination and reasonable additional imaging evaluation. For symptomatic breast lesions, the assessing threshold of category Ⅱ or Ⅲ should be improved, and category Ⅳ should be reduced. But BI-RADS has its limitation. We propose that corresponded classification should be drawn according to every application’s condition.
