    Abstract:
    INTRODUCTION: Breast cancer is the commonest cancer in women and represents a significant problem from the clinical and public health perspectives. The aim of this paper is to report our experience of transitioning from screen-film mammography (SFM) to computed radiography mammography (CRM), and finally to full-field digital mammography (FFDM), and to evaluate the performance of these three different types of mammographic systems. METHODS: A total of 2,734 mammograms using the three different systems were carried out at the University of Malaya Medical Centre. These examinations were evaluated based on time from start of examination to reporting, image quality, archiving, reject and repeat rates and overall diagnostic accuracy for SFM, CRM and FFDM. RESULTS: The time taken from the start of the examination to the radiologist interpretation and reporting were faster in both FFDM and CRM, compared to SFM. Image contrast with better contrast detail was almost equivocal for both CRM and FFDM, but lower for SFM. Easier image storage and archiving were available for CRM and FFDM in the form of magnetic optical discs, rather than hard copy storage as in SFM. The reject rate for FFDM was zero percent, compared to CRM and SFM which were two percent and two percent, respectively. The repeat rate for FFDM, CRM and SSFM was zero percent, 0.1 percent and 1.5 percent, respectively. Overall diagnostic accuracy of FFDM, CRM and SFM were comparable as no cancers were missed on all three systems as double blinded reporting was done. CONCLUSION: FFDM does improve quality of mammography service by providing better workflow time and archiving system, with good diagnostic accuracy.
