Comparison of Contrast-enhanced Spectral Mammography (CESM) to MRI in Screening High Risk Women for Breast Cancer

High risk screening MRI will be performed as part of the patient's routine care.

After the MRI is complete, the patient will be brought to the mammography department for the contrast enhanced mammogram. The contrast enhanced mammogram will be independently interpreted by two study radiologists (randomly assigned) who are blinded to the MRI. They will then compare to the MRI to determine clinical follow-up. Any finding seen on MRI will be followed according to the MR protocol. Any finding seen on CESM only, will have a diagnostic work-up with mammography and ultrasound. If this work-up is negative, then follow-up CESM exams will be performed. Each patient will be followed for 2 years to determine sensitivity and specificity for both modalities.
