RSNA 2011: Failure to match detector to breast size leads to increased radiation dose
Matching breast size to the appropriate detector size is important, according to an evaluation of mammography screening results at a single institution over a 6-week period. In this study of 864 women undergoing mammography, data were gathered on breast size, detector size, number of views obtained, and mean glandular dose (MGD) of radiation per breast. Women with large breasts screened on a small detector received significantly more views and significantly more radiation than women screened with an appropriately sized detector. Women with small breasts screened with a large detector also received significantly more views than those with an optimally sized detector, but these patients were not exposed to a significantly greater radiation dose. The data reinforce the importance of matching breast size to detector size in order to provide minimal radiation dose exposure.
