Distribution of mammography equipment and mammographies in Rio de Janeiro State, Brazil, 2012 and 2013. Epidemiol. Serv. Saúde [online]. 2015, vol.24, n.1, pp.105-114. ISSN 2237-9622.


to describe the distribution of mammography equipament and mammographies performed in Rio de Janeiro State.


this was a descriptive study based on information from the National Register of Health Establishments (CNES) and the Breast Cancer Information System (SISMAMA), 2012/2013.


there were 546 mammography machines in use, 142 (26.0%) of which serve the Unified Health System (SUS); no shortage of mammography machines was found - including in SUS services - in the state's regions according to the national coverage parameter. Most mammography machines and exams were concentrated in Metropolitan Region I which had the highest ratio of SUS population and mammographies (170 231) with 228.3 tests per machine per annum on average.


there is no shortage of mammography equipment despite inequalities in their distribution; however, average annual equipment productivity was low.
