摘　　要：目的探讨乳腺癌钙化在数字化全景乳腺摄影中的特征,以提高乳腺癌的诊断水平。方法回顾性分析2012年8月~2014年9月于我院经手术病理证实的46例乳腺导管癌患者的临床资料及乳腺全景X线摄影资料。结果病理结果证实,46例乳腺导管癌患者中,8例为钙化性导管癌;38例为浸润性导管癌,其中一级浸润性导管癌12例,二级浸润性导管癌15例,三级浸润性导管癌11例。乳腺全景X线摄影显示,46例患者的乳腺均具有散在分布的微小钙化。将全景X线摄影征象（钙化形态、钙化总数、单位面积钙化数,合并肿块、腋窝淋巴结肿大、淋巴结转移情况）与病理结果进行对比,结果发现,不同病理分级间单位面积钙化数和淋巴结转移情况有显著差异（P〈0.05）,其他指标均无显著差异。结论全景数字化乳腺X线摄影可显示乳腺癌的微小钙化,为乳腺癌的早期诊断提供依据。Objective To investigate the characteristic of breast carcinoma calcification in full-field digital mammography so as to promote diagnosis of breast carcinomas.Methods Retrospective analysis of clinical materials and full-field digital mammographs was made on 46 breast ductal carcinoma patients who have been confirmed by surgical pathology in the hospital from August 2012 to September 2014.Results According to the pathological results,there were 8 cases of ductal carcinoma in situ and 38 cases of infiltrating ductal carcinomas（8 cases in stage Ⅰ;15 in Stage Ⅱ;11 in Stage Ⅲ） among 46 breast ductal carcinoma patients.The full-field digital mammographs revealed scattered microcalcification in all the 46 patients.Through comparison of the abnormalities in mammographs and the pathological results,it can be found that the calcification per unit area and lymph node transfer were statistically significant differente（P〈0.05） in different pathological stages;other indicators had no statistically significant difference.Conclusion The full-field digital mammography can make microcalcification revealed and provide a basis for the early diagnosis of breast carcinomas.
