DICOM mammograms оf patients with BIRADS 4,5

The database contains mammograms of patients with BIRADS 4 and 5: breast cancer was subsequently verified histologically. BI-RADS 4 Suspicious Abnormality - Biopsy Should Be Considered: This category is reserved for findings that do not have the classic appearance of malignancy but are sufficiently suspicious to justify a recommendation for biopsy.BI-RADS 4 has a wide range of probability of malignancy (2 - 95%). BI-RADS 5 Highly Suggestive of Malignancy.Appropriate Action Should Be Taken:BI-RADS 5 must be reserved for findings that are classic breast cancers, with a >95% likelihood of malignancy.本数据库收录了BIRADS（乳腺影像报告和数据系统，Breast Imaging Reporting and Data System）4类与5类患者的乳腺钼靶影像，所有病例后续均经组织病理学证实为乳腺癌。 BI-RADS 4 可疑异常，建议考虑活检： 该分类适用于未呈现典型恶性征象，但具备足够可疑程度、足以建议实施活检的影像学表现。BI-RADS 4类的恶性概率范围为2%至95%。 BI-RADS 5 高度疑似恶性，需采取适宜处置措施： 该分类仅适用于呈现典型乳腺癌征象、恶性概率超过95%的影像学表现。
