Abstract: Objective:Analysis of the clinical diagnostic value of color Doppler ultrasound and molybdenum target imaging in the detection of BIP and DCIS.Methods:The color ultrasound，molybdenum target and pathological data of 141 patients were reviewed，including BIP（69 cases，71 lesions）and DCIS（67 cases，67 lesions）.The detection rates of BIP and DCIS indicated by color ultrasound and molybdenum target were compared.Results:The detection rate of tumor with calcification and simple tumor type signs indicated by color ultrasound was 5.63% and 91.55% respectively for BIP，89.55% and 5.97% for DCIS，while the detection rate of two positive characteristics indicated by molybdenum target was 60.56% and 38.28% for BIP，68.66% and 31.34% for DCIS，In the overall analysis of positive signs，compared with color ultrasound.There were statistical differences in the diagnosis of BIP and DCIS（P<0.05）.Conclusion:In the diagnosis of BIP and DCIS，more attention should be paid to the examination value of molybdenum target，but the two examinations complement each other and are equally important.
