OBJECTIVE: The purpose of this article is to evaluate the impact on the diagnosis of @entity0 of implementing full-field digital mammography (FFDM) in a multidisciplinary breast pathology unit and, 1 year later, the addition of a computer-aided detection (CAD) system. MATERIALS AND METHODS: A total of 13,453 mammograms performed between January and July of the years 2004, 2006, and 2007 were retrospectively reviewed using conventional mammography, digital mammography, and digital mammography plus CAD techniques. Mammograms were classified into two subsets: screening and diagnosis. Variables analyzed included @entity5 detection rate, rate of in situ @entity189 , @entity5 size at detection, biopsy rate, and positive predictive value of biopsy. RESULTS: FFDM increased the @entity5 detection rate, albeit not statistically significantly. The detection rate of in situ @entity189 increased significantly using FFDM plus CAD compared with conventional technique (36.8% vs 6.7%; p = 0.05 without Bonferroni statistical correction) for the screening dataset. Relative to conventional mammography, @entity5 size at detection decreased with digital mammography (T1, 61.5% vs 88%; p = 0.018) and with digital mammography plus CAD (T1, 79.7%; p = 0.03 without Bonferroni statistical correction). Biopsy rates in the general population increased significantly using CAD (10.6/1000 for conventional mammography, 14.7/1000 for digital mammography, and 17.9/1000 for digital mammography plus CAD; p = 0.02). The positive predictive value of biopsy decreased slightly, but not significantly, for both subsets. CONCLUSION: The incorporation of new techniques has improved the performance of the breast unit by increasing the overall detection rates and earlier detection ( @entity5 ), both leading to an increase in interventionism.
