However, MRI is recommended for the surveillance of BRCA1/2 mutation carriers [27, 28]; MRI has a high negative predictive value for invasive carcinoma [29] and can be useful for selecting women who do not need to undergo sentinel lymph node biopsy (because occult carcinomas that have not been identified using MRI have a lower probability of lymph node metastasis) [30]. This evidence concerns the gene BRCA1 and invasive carcinoma.
