    21158 screening mammograms were obtained, 10024 acquired using full field digital mammography (FFDM) and 11134 acquired using film-screen mammography. For each mammogram, data were collected on recall for further assessment due to detection of microcalcification, use of needle biopsy, and presence of microcalcifications in biopsy specimens. 61.5% of women who had a core biopsy following digital mammography had microcalcifications detected, compared with 65.8% for analogue mammography but this difference was not significant (p=0.71). Rates of detection of microcalcifications in women screened by the two methods were similar. It was also found that the recall rate for assessment for women screened digitally (6.1%) was significantly higher than the recall rate for those screened by analogue mammography (3.3%), 95% confidence interval 2.2% - 3.4%. Screening using digital mammography leads to a higher recall rate for assessment than analogue mammography, although similar rates of detection of microcalcifications occur with both imaging modalities. © 2010 Springer-Verlag.
