To Evaluate the Value of Mammography and CT in the Diagnosis of Breast Disease

Objective To discuss the value of mammography and CT in the diagnosis of breast disease. Methods Forty-seven cases were confirmed by pathology, including breast malignancy neoplasm twenty cases (age mean 51 years) and benign diseases twenty-seven cases (age mean 40.6 years). All cases underwent plain scanner and 26 cases underwent contrast-enhanced scanner with use of a Helical CT (TOSHIBA Xpress / GX, Japanese ). For each patient, a field view was chosen that would depict the whole breast, as well as the ipsilateral axillary and internal mammary chains. All cases were referred for mammography using routine craniocaudal and mediolateral oblique views.Results CT was superior to mammography in cysto-wall mass, little, huge breast, dense breast, mass border, chest-wall invasion, deformed adipose space. mammography was superior to CT in microcalcification. The sensitivity, specificity, positive predictive value, and negative predictive value of mammography, CT and both were 65%, 85%, and 95%; 51.9%, 81.5%, and 92.6%; 50%, 77.3%, and 90.5%; 66.7%, 88% and 96.2%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of CT and clinical examination diagnosing axillary lymph node metastasis were 80% and 80%; 90% and 80%; 88.9% and 80%; 81.8% and 80%, respectively.Conclusion CT has a higher accuracy than mammography in detecting and differentiating breast diseases. CT could make up deficiency of mammography on the whole.
