Brief Summary
One of the primary criticisms of mammography is that it leads to unneeded stress and anxiety from identification and biopsy of non-cancerous findings. Contrast-enhanced mammography (CEM) has the potential to significantly reduce biopsy rates for commonly seen benign breast lesions while preserving very high cancer detection. The investigators propose a prospective clinical study of patients with diagnostic mammograms rated as BIRADS 4A or 4B and scheduled for a biopsy, in which, prior to undergoing their scheduled biopsy, a CEM procedure is performed. The investigators will test the primary hypothesis that for soft tissue lesions (i.e. masses, asymmetries, architectural distortions) initially rated BI-RADS 4A/4B adding CEM will reduce, by at least 20%, the number of biopsy recommendations for actually benign cases and, at the same time, provide a negative predictive value (NPV) higher than 95%.

Outcome Measures
Primary Outcomes (1)
Negative Predictive Value (NPV)
The investigators will estimate and compare the changes in NPV of pre- and post CEM-based recommendations (where NPV is the proportion of pathology verified benign lesions out of post-CEM-downgraded to BIRADS 3 or lower).

Study Arms (1)
contrast enhanced mammography
EXPERIMENTALWomen who have been recently diagnosed with a suspicious abnormality for which they have scheduled a breast biopsy and meet inclusion criteria will be invited to have a contrast enhanced mammography before their scheduled biopsy procedure.
Interventions
Dual-energy contrast images; low-energy CEM images will be obtained with a kilovoltage below 35 kVp while the high-energy images will be obtained with 45-49 kVp.The average glandular dose of the CEM procedure is approximately 2.44 mGy per view
standard FDA-approved low osmolarity Iodine contrast agent with 350-370 mg/ml
Eligibility Criteria
You may qualify if:
- Subject is female of any race and ethnicity
- Subject is ≥30 years old
- Subject is diagnosed with a suspicious breast abnormality and is scheduled for an imaging directed breast biopsy.
You may not qualify if:
- Subject is unable or unwilling to undergo informed consent
- Subject has a breast implant in the breast of interest
- Subject is pregnant
- Subject is breast-feeding
- Subject is actively being treated for cancer of any type with chemotherapy
- Subject has reduced kidney function with eGFR \< 30.
- Subject has had a prior reaction to iodinated contrast; thus a known allergy to iodinated contrast
