摘要目的确定恶性肿瘤总体发病率尤其是根据BIRADS标准在≥70岁因乳腺钙化接受立体定向活检女性中的恶性率。方法回顾性研究了6 839例≥70岁女性病人的14 577份乳腺钼靶报告并从中挑选出215例病人针对可疑钙化行立体定向活检的231份。凡是缺失图像或者病理结果的病例,以及与肿瘤、结构扭曲或不对称有关的钙化均予以 Abstract Objective To determine the overall incidence of malignancies, especially in women with stereotactic biopsies of breast calcification at ≥70 years according to BIRADS criteria. METHODS: A retrospective study of 14 577 breast mammographic targets from 6 839 women ≥70 years of age was conducted and out of 231 patients were selected for their identification of 231 suspected stereotypical biopsies of suspected calcification. All cases of missing images or pathological findings, as well as calcifications associated with tumor, structural distortion or asymmetry
