Breast MRI is a powerful tool when used appropriately; it the most sensitive imaging modality for detection of breast cancer (exception: mammography better at detecting DCIS), it can be used for complex problem-solving, it can help screen high-risk women, it is one of the best modalities to monitor response to chemotherapy, and MRI results change treatment plans in 15-30% of breast cancer patients

MRI has low specificity, however, resulting in many false positives, more unnecessary biopsies, and delays in definitive treatment

As a result, *breast MRI is not routinely used*
