Current and potential roles for MR imaging in the management of breast disorders are reviewed along with the specific technical requirements for each application. Major topics include (1) evaluating breasts before biopsy to reduce the number of surgical biopsies for benign lesions, (2) staging of breast carcinoma in breast conservation candidates, (3) evaluating breasts with inconclusive conventional imaging, (4) coordination of minimally invasive surgery, and (5) evaluating silicone implant integrity.
