Breast MRI for Newly Diagnosed Breast Cancer:Impact on Re-excision Lumpectomy

This is a prospective pragmatic trial randomizing women diagnosed with early stage breast cancer to MRI versus no breast MRI. Data analyzed will include medical record information abstracted from the clinical records. Date and modality of all imaging performed, malignancy(s) identified, abnormalities identified, image guided procedures performed, surgical procedures performed and pathology results. The primary aim of this study is to assess if the use of pre-operative MRI can reduce the incidence of re-excisions required to achieve clear margins in women with newly diagnosed early stage breast carcinoma.
