The Arkansas Mammography Data Collection Project, funded by the Arkansas Department of Health, aimed to determine the mammography screening patterns throughout the state of Arkansas. Data were obtained from 92 mammoraphy centers out of 112 centers (82%). A total of 157,976 mammography data sets were obtained for 148,586 women. Mammography rate was 22.7% for women 40 years and older and 24.1% for women 50 years and older. Mammography rates per county varied from 0.3% to 42.6%. The overall low rate of mammography utilization reflects the need to intensify public health interventions and continuous evaluations of these interventions.
