118 patients with proven unilateral breast cancer and negative controlateral breast at physical examination, US and x-ray mammography underwent CE-MRM to evaluate the controlateral breast. Axial 3D T1-W GRE images were acquired before and after gadobenate dimeglumine injection. Images were evaluated by two readers in consensus and compared with histological findings. CE-MRM depicted lesions in the controlateral breast in 28/118 patients. Malignancy was confirmed for 22 lesions. This study demonstrates the need to carefully evaluate the controlateral breast in patients with known unilateral breast cancer.
