    OBJECTIVE. The selection of breast cancer patients as candidates for nipple-sparing mastectomy (NSM) is dependent on the preoperative detection of neoplastic involvement of the nipple-areola complex (NAC). This cross-sectional study was designed to evaluate the accuracy of preoperative breast MRI as a noninvasive method to predict neoplastic involvement of the nipple. MATERIALS AND METHODS. We included 165 female breast cancer patients with a surgical plan that included total mastectomy or breast conservation surgery with the removal of the NAC. All patients underwent MRI before surgery on a 1.5-T unit with a 4-channel in vivo dedicated surface breast coil. One radiologist who was blinded to the results of the histologic evaluations of the specimens evaluated the MRI studies. RESULTS. Of the 170 mastectomy specimens evaluated, 37 (21.8%) had neoplastic involvement of the NAC. The MRI findings of enhancement between the index lesion and the NAC and of nipple retraction were considered statistically significant predictors of nipple involvement in breast cancer patients (p < 0.01 and p = 0.01, respectively). The negative predictive value of the combination of these MRI findings was 83.3%. CONCLUSION. Breast MRI is a safe noninvasive method to preoperatively evaluate breast cancer patients eligible for NSM with a high specificity and a high negative predictive value when enhancement between the index lesion and the nipple and nipple retraction are analyzed.
