目的：其目的是评估的准确性BI-RADS类别3 - 5在乳腺超声（US）作为一线imaging method.Materials和方法：5077检查的连续，混合集体的症状和无症状的患者进行。结果：BI-RADS 3、4、5的恶性病变PPV分别为0.03、0.48、0.97。当BI-RADS 4和5例被认为是可疑的，良性与恶性结果的比例对应于1：1.8。BIRADS 3 ~ 5级病变的敏感性、特异性和准确性分别为0.92、0.85和0.87。结论：根据ACR BI-RADS分类，超声在不增加不必要活检的情况下，可用于鉴别良恶性病变。
Purpose: The aim was to evaluate the accuracy of BI-RADS categories 3 - 5 in breast ultrasound (US) as the first-line imaging method.Materials and Methods: 5077 examinations of a consecutive, unselected and mixed collective of symptomatic and asymptomatic patients were performed. Of these examinations, 835 cases of BIRADS 3 - 5 could be analyzed.Results: The PPV with respect to a malignant lesion for BI-RADS 3, 4, 5 was 0.03, 0.48, and 0.97, respectively. When BI-RADS 4 and 5 cases are considered to be suspicious, the ratio of benign to malignant findings corresponds to 1:1.8. Analyzing BIRADS 3 - 5 lesions, the sensitivity, specificity and accuracy are 0.92, 0.85, and 0.87, respectively.Conclusion: The data support the feasibility of US for discriminating malignant from benign findings corresponding to the ACR BI-RADS classification without excessively increasing the number of unnecessary biopsies.
