摘　　要：目的探讨超声与数字钼靶X线摄影及两者联合对不同级别乳腺导管原位癌(DCIS)的诊断价值。方法收集我院经手术病理确诊的DCIS患者38例,比较超声与数字钼靶X线摄影及两者联合对不同级别DCIS的诊断符合率及微钙化特征。结果高级别DCIS20例,低级别和中级别DCIS18例;单纯DCIS28例,DCIS伴微浸润10例。超声对DCIS、高级别DCIS、低级别和中级别DCIS诊断符合率分别为73.68%(28/38)、90.00%(18/20)和55.56%(10/18)。数字钼靶X线摄影对DCIS、高级别DCIS、低级别和中级别DCIS诊断符合率分别为76.32%(29/38)、90.00%(18/20)、61.11%(11/18)。两者联合对DCIS、高级别DCIS、低级别和中级别DCIS诊断符合率分别为78.95%(30/38)、90.00%(18/20)、66.67%(12/18)。超声与数字钼靶X线摄影对DCIS的微钙化检出率均为57.89%(22/38)。结论超声与数字钼靶X线摄影对DCIS的诊断符合率与微钙化发现率相似,直径>20mm的DCIS常伴有微浸润,直径<10mm无钙化的DCIS易于漏误诊。Objective To assess the diagnostic value of ultrasonography（US）,digital mammography（DM）and the combination of them（US＋DM）in ductal carcinoma in situ（DCIS）of breast.Methods Thirty-eight patients of DCIS diagnosed with pathology were selected.The diagnostic yield and the microcalcification characteristics of different grades DCIS with US,DM and US＋DM were compared.Results Twenty patients had high-grade DCIS,18 were low-intermediate-grade DCIS.Lesions in 28 patients were pure DCIS and 10 with microinvasion.The diagnostic yield for US to DCIS,high-grade DCIS,low-intermediate-grade DCIS was 73.68%（28/38）,90.00%（18/20）and 55.56%（10/18）,respectively.The diagnostic yields for DM to DCIS,high-grade DCIS,low-intermediate-grade DCIS was 76.32%（29/38）,90.00%（18/20）and 61.11%（11/18）,respectively.The diagnostic yield for US＋DM to DCIS,high-grade DCIS,low-intermediate-grade DCIS was 78.95%（30/38）,90.00%（18/20）,66.67%（12/18）,respectively.Detection yield of microcalcification on both US and DM was 57.89%（22/38）.Conclusion The diagnostic yield and detection yield of microcalcification for US and DM to DCIS are similar,high-grade DCIS in diameter larger than 20 mm is associated with microinvasion and those smaller than 10 mm without microcalcification are often skipped over or misdiagnosed.
