Abstract

Magnetic resonance imaging (MRI) is not recommended for characterizing indeterminate focal lesions, detected by standard imaging, because of its relatively low specificity (high rate of false-positive results) and its cost. While its sensitivity exceeds 90 %, false-negative results may occur in infiltrating carcinomas (<5 %) or carcinomas in situ (rates between 5 and 40 %). The primary indications of MRI are: suspicion of local relapse in a treated breast (sensitivity and specificity > 90 %), research of primary breast tumor (metastatic axillary lymph nodes with normal standard imaging), research of residual carcinoma after neoadjuvant chemotherapy, staging of patients with Paget's disease (normal mammography). MRI is the best modality for staging breast carcinoma (multifocality, extensive in situ component), but its routine indication is still problematic because of the need for obtaining histologic proof for lesions only detected by MRI (interventional procedures). At this time, screening with MRI is evaluated in women at high genetic risk of breast cancer.
