Screening Contrast-Enhanced Mammography as an Alternative to MRI

Brief Summary

There are women for whom a screening breast MRI is clinically recommended, but not feasible either due to patient factors (body habitus, pacemaker or other implant, claustrophobia) or access (cost, other constraints). Contrast-enhanced mammography (CEM) is a potential alternative to MRI for screening that uses updated standard mammography equipment to obtain low- and high-energy images after intravenous injection of iodinated contrast (as used in CT scanning). The investigators seek to validate screening CEM as an alternative to screening MRI.
