Peer review of mammography interpretations in a breast cancer screening program.

Mammograms from a statewide screening program were subjected to a blind review by a panel of expert mammographers. Ninety-five percent (173/182) of original normal mammograms and 53% (164/311) of original abnormal mammograms were reread as normal. In comparison with the expert panel community radiologists were more likely to request a repeat mammogram in 6 months than to interpret a mammogram as normal or address their uncertainty with an immediate diagnostic workup.
