• Contrast-enhanced mammography (CEM) detected fewer additional lesions than magnetic resonance imaging (MRI), with 29% false positives.• CEM failed to detect five of six additional cancers: two invasive ductal cancers (5 and 7 mm), two ductal carcinoma • Reasons for CEM false negatives included lesion out of field of view (• Despite producing 49% false positives, MRI detected all six additional cancers.• CEM may not be as sensitive as MRI for breast cancer staging.
