A Survey of Patient Doses from Digital Mammography Systems in the UK in 2007 to 2009

Patient dose data from across the UK were collated, and the information relating to full-field digital mammography systems were analysed, and compared with overall results for film-screen systems For CR systems, the average mean glandular doses was 2.19 ± 0.07 mGy which was similar to the average for film screen systems 2.15 ± 0.01 mGy The average patient dose for DR systems was 1.46 ± 0.02 mGy approximately 32% lower than for film screen systems When different DR systems were compared, the Sectra MDM L30 and the Siemens Novation and Inspiration had the lowest average mean glandular dose, at 0.95 ± 0.02 mGy, 1.16 ± 0.05 mGy and 1.21 ± 0.07 mGy, respectively It was shown that for DR systems the MGD to the standard breast was broadly correlated with the average MGD for oblique views of 50-60mm thick breasts, while the correlation for CR systems was much lower.
