Comparative studies on mammography, CT and pathologic changes of patients with breast neoplasm

Objective:To investigate the clinical value of CT and digital mammography for diagnosis of breast neoplasm.Methods:Forty-five patients suspected as breast cancer underwent CT imaging and mammography,and compared to the results of histopathological examination.The differences in diagnosis were compared with these examinations.Results:The positive detection rates of CT and mammography were 84.4%(38/45)and 93.3%(42/45)respectively.The combination positive detection rate was 97.8%(44/45).In detecting breast cluster of calcification,the sensitivity of mammography was 73.3%(33/45),which was better than CT scan(46.7%,21/45).The axillary lymph metastases were found in 34 patients.In detecting the axillary lymph metastases of the breast carcinoma,the sensitivity of CT scan was 88.2%(30/34),which was better than mammography(67.6%,23/34).Conclusions:The mammography and CT play the important role in diagnosis of breast neoplasm and showed the different character.The mammography combined with CT can improve the accurate rate of diagnosis.
