Abstract: Objective To investigate the clinical value of MRI in the preoperative evaluation of breast cancer compared with mammography and ultrasonography. Methods A total of 35 patients with breast cancer were examined preoperatively with dynamic contrast enhanced MRI, mammography and ultrasonography. The findings were evaluated and compared with surgical biopsy. Results The detection rates of breast cancer with MRI, mammography and ultrasonography was 100%, 74.29% and 82.86%, respectively. MRI, mammographic and ultrasonographic measurement of tumor size had correlation coefficient to pathologic findings (r=0.94, 0.87, 0.70, respectively). The sensitivity, specificity, and accuracy of detection of intraductal spread of MRI, mammography and ultrasonography was 100%, 80.00% and 88.57% (P＜0.05), 66.67%, 95.00% and 82.86% (P＞0.05), 33.33%, 95.00% and 68.57% (P＞0.05), respectively. Conclusion MRI can detect breast cancer, especially intraductal spread more sensitively than mammography and ultrasonography.
