64-year-old female was called back from screening. (A) Spot magnification views in the CC and ML projections show two groups of suspicious microcalcifications (black circles), one of which is associated with a vague focal asymmetry which persists on spot compression (B); same day CEM study again shows the two groups of microcalcifications (black circles) on the LE images (C) but with no suspicious enhancement on RI. A stereotactic needle biopsy was performed confirming low grade DCIS. This case illustrates how CEM can protect sensitivity in the example of DCIS on LE mammogram by identifying the morphologic abnormality of microcalcifications before assessing enhancement on subtraction mammogram of CEM (no enhancement is identified in this case)
