目的：分析乳腺导管原位癌(DCIS)的 X 线表现特点,加强对 DCIS X 线征象认识。方法收集浸润性导管癌(IDC)158例,乳腺 DCIS 27例、导管原位癌伴微浸润(DCIS-MI)14例,对其 X 线摄影征象进行分析。结果 DCIS 钙化的发生率和单纯钙化的发生率均显著大于 IDC(P 值均<0.05)；DCIS 和 IDC 在钙化形态上无明显差异(P >0.05),均以颗粒点状多见；在钙化分布上差异显著(P <0.05),DCIS 中线样和“V”形节段性分布所占比例较高,IDC 中钙化呈簇状分布所占比例较高。结论 DCIS 主要 X 线征象为单纯钙化,沿导管呈线形或“V”形分布是其特征。

Objective To analyze the mammographic findings of ductal carcinoma in situ,and to improve DCIS diagnosis.Methods 1 58 cases of infiltrating ductal carcinomas,27 cases of DCIS and 14 cases of DCIS with microinvasion identified by postoperative pathological were collected,and their mammographic data were analyzed etrospectively.Results There were significantly more calci-fication and pure calcification in DCIS group than in IDC group(both P <0.05 ).And have no statistically significant difference be-tween those two diseases for the shap of calcification(P >0.05),both of them mostly showed granula and punctate calcification.There were statistically significant difference those two diseases for the distribution of calcification (P <0.05),the linearity and V-shaped segmental distribution occupies a relatively high percentage in DCIS while the cluster-like calcification occupies a relatively high percentage in IDC.Conclusion Pure calcification is mainly mammographic feature of DCIS.The characteristic of calcification is distribute along duct.
