Abstract: 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.
