A Comparative Study on Digital Mammography and Ultrasonography in Diagnosis of Breast Ductal Carcinoma

Objective To investigate the value of digital mammography and ultrasonography in diagnosis of breast ductal carcinoma.Methods 53 cases of ductal carcinoma were retrospectively analyzed.The digital mammography and ultrasonography were performed in all cases.The diagnosis of digital mammography and ultrasonography was divided into probably malignant,indeterminate,probably benign,and negative.According to surgical and histopathological outcomes,a comparative study on the value of digital mammo-graphy and ultrasonography was performed.Results There are 36 cases and 33 cases of probably malignant,4 cases and 5 cases of indeterminate,7 cases and 10 cases of of probably benign,6 cases and 5 cases of negative diagnosed by digital mammography and ultrasonography respectively.The accuracy of digital mammography and ultrasonography were 67.9%(36/53) and 62.3%(33/53) respectively.The accuracy of digital mammography associated with ultrasonography was 88.7%(47/53).Conclusion Digital mammography and ultrasonography are valuable in the diagnosis of breast ductal carcinoma.The diagnostic accuracycan be improved by the combination of the two methods.
