Objective:To evaluate the significance of the use of mammography or ultrasonography alone in the diagnosis of breast with calcification,and to explore whether the combination of the two can improve the efficiency of diagnosis.Methods:Through mammography and ultrasonography exmination,122 patients all have calcified lesions,who had not undergone biopsy,physiotherapy,surgery and Chemotherapy.These cases confirmed by pathology or postoperative puncture were collected.SIMENS full digital mammography,photography enlarged partial point pressure if necessary.The size,location,number,shape and distribution of breast lesions and Calcification were abserved and recorded.The results were analyzed.Using the GE LOGIQ 9 color Doppler ultrasonography,record the size of the lesion,edge,shape,internal echo,ratio.And then color Doppler flow imaging(CDFI)to observe the surrounding tumor and internal blood flow,comprehensive analysis of lesions to determine its Benign and malignant.SPSS 19.0 software package for statistical methods and data processing counting date with X2 test(if not meet the X2 test,using Fisher's exact probability method)to P<0.05 for the difference was statistically significant,P<0.01 for the difference with statistically significant.Result:122 cases of breast with calcification disease pathological diagnosis:Mammography sensitivity calcified breast disease diagnosis,specificity,positive predictive value,negative predictive value,false positive rate,false negative rate,accuracy were 85.3%,70.2%,82.1%,75.0%,29.8%,14.7%,79.5%;The sensitivity,specificity,positive predictive value,negative predictive value,false positive rate,false negative rate,accuracy of ultrasonography were 78.7%,66.0%,78.7%,66.0%,34.0%,21.3%,73.8%.The combined using was 94.6%,93.6%,95.6%,91.7%,6.4%,5.3%,94.3%respectively.The combination of the two can improve the accuracy of breast calcification lesions(P<0.05).Conclusions:1.The calcification characteristics to identify benign and malignant breast disease in Mammography,which has a certain significance.Color Doppler flow imaging observation of blood flow signal diagnosis of breast cancer has a certain guiding value.2.If mammography and ultrasonography were combination,the diagnosis of breast calcification lesions is superior to its individual diagnosis.
