Breast MRI is useful for screening women with genetic mutations that confer a very high risk for breast cancer. The figure depicts a breast MRI that was performed on a BRCA-1 gene carrier, revealing a focal circumscribed mass in left breast not visible on mammography (arrow). MRI-guided core biopsy confirmed an invasive ductal carcinoma.
BRCA: breast cancer susceptibility gene; MRI: magnetic resonance imaging.
