Purpose:
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).
Materials And 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.
Conclusion:
Our findings indicate equivalence of high-resolution digital phosphor storage plate mammography (CR) and full-field digital mammography (a-Se) (DR).
