In certain situations, clinical examination, mammography and ultrasonography have some limitations; due to factors in the modality or breast parenchyma MR imaging has an important role in clinical practice; both in lesion characterization and tumor staging.

. Post contrast MRM can give relevant additional information in patients with mammographically dense breasts, or inhomogeneous tissue on sonography, or both. Both qualitative and quantitative criteria are needed for lesion interpretation. Preoperative post contrast breast MRI has the potential to reveal mammographically & sonographically hidden multifocal, multicenteric, or contralateral breast carcinoma
