[DR (a-Se) versus CR (DLR)--is an improvement of the accuracy possible? A retrospective histologic analysis (n = 100)].
OBJECTIVE
A retrospective clinical-histological study to determine the diagnostic accuracy using high-resolution digital phosphor storage plates (CR) (hardcopy) and full-field digital mammography (DR) (hardcopy) for microcalcifications and focal lesions (BI-RADS category 4 or 5) (n = 100).


METHODS
From 01/2004 to 06/2004, 100 patients underwent digital storage plate mammography (CR) and, after diagnosis and preoperative wire localization, full-field digital mammography (a-Se) (DR) with the same exposure parameters. Five investigators retrospectively determined the diagnosis after the operation from randomly distributed mediolateral views (hardcopy reading). These results were correlated with the final histology.


RESULTS
The accuracy of digital storage plate mammography (CR) and full-field digital mammography (DR) was 73% and 76% for all findings (n = 100), 74%, 78% for microcalcifications (n = 50) and 72%, 74% for focal lesions (n = 50). The overall results showed no difference.


CONCLUSIONS
Our findings indicate equivalence of high-resolution digital phosphor storage plate mammography (CR) and full-field digital mammography (a-Se) (DR).
