Abstract: Objective To investigate the diagnostic value of mammography and ultrasonography in patients with invasive tubular breast carcinoma.Methods One hundred and ninetyseven patients with breast diseases were reviewed retrospectively. They were divided into premenopausal group and postmenopausal group. Pathologic result were chosen as gold standard. The diagnostic accuracy of mammography and ultrasonography was compared.Results In the premenopausal group: sensitivity, specificity and accuracy rates of ultrasonography were 87.7%, 90.7% and 89.4% respectively; sensitivity, specificity and accuracy rates of mammography were 63.2%, 89.3% and 78.0% respectively. In the postmenopausal group: sensitivity, specificity and accuracy rate of ultrasonography were 90.0%, 93.4% and 91.9% respectively; sensitivity, specificity and accuracy rate of mammography were 86.7%, 90.8% and 90.0% respectively.Conclusion Ultrasonography has greater value clinically in diagnosing invasive tubular breast carcinoma. Sensitivity of mammography in premenopausal group is obviously lower than that in postmenopausal group. In premenopausal group, sensitivity and accuracy rate of ultrasonography are obviously higher than those of mammography.
