This study is one of a few that has performed a head-to-head comparison of the ability of CEM with that of MRI for the detection of additional foci of malignancy not previously detected on conventional imaging in a sample of women with at least one biopsy-proven invasive breast cancer. Our results suggest that MRI may be superior to CEM, as it enabled the detection of all six lesions while CEM detected just one. The fact that two of the five additional cancers missed by CEM were multicentric cancers and one of them was 30 mm in size is cause for concern (Fig. While the effect of detection of the additional cancers on the surgical plan is not evaluated in this paper, the ability of preoperative imaging to differentiate unifocal from multifocal or multicentric breast cancer has important implications, for both patient treatment and prognosis [
