The primary objective of this study is to compare the diagnostic accuracy of Digital Breast
Tomosynthesis (DBT) versus that of Contrast Enhanced Magnetic Resonance Imaging (CEMRI) in
determining the size of breast cancer preoperatively.
Secondary objectives include:
1. Comparing the operating characteristics of each combined imaging protocol with respect
to the reference standard, i.e. histopathologic assessment, of additional non-index
2. Comparison of re-excision rates based on estimated disease extent from adjunctive CEMRI
vs. adjunctive DBT.
3. Evaluation of patient satisfaction with regard to the adjunctive modality (DBT vs.
