Fig. 1A. 49-year-old woman who presented to diagnostic center with no
clinical complaints. Film-screen mammogram (not shown) was interpreted as
having normal findings. Photographic magnification of full-field digital
mediolateral mammogram after electronic magnification reveals faint cluster of
indeterminate microcalcifications (arrow) in lower breast. Cluster
was not visible, even retrospectively, on film-screen mammography. Patient was
called back on basis of full-field digital mammography results and underwent
biopsy for microcalcifications with stereotactic guidance.
