MR Imaging of the Ipsilateral Breast in Women with Percutaneously Proven Breast Cancer

Abstract

MR imaging identified additional sites of ipsilateral cancer in 27% of women with percutaneously proven breast cancer. The yield was highest in women with a family history of breast cancer or infiltrating lobular histology in the index cancer. Change after biopsy was infrequent and did not interfere with the MR imaging interpretation.
