Fig. 2A. —38-year-old woman with indeterminate microcalcifications in
left breast; biopsy revealed benign fibrocystic change. Manipulation of
computer display on digital system allows microcalcification to be better seen
and therefore more precisely targeted. Digital stereotactic image.

Fig. 2B. —38-year-old woman with indeterminate microcalcifications in
left breast; biopsy revealed benign fibrocystic change. Manipulation of
computer display on digital system allows microcalcification to be better seen
and therefore more precisely targeted. Same images as in A after
magnification and contrast adjustment (B), inverted (black on white,
C), and with further magnification (D).
