^*Sites 1 and 2 did not compile performance reports after 2003 and 2005, respectively, thus all the data presented here for these sites represents performance reports sent in 2003 or 2005. Summary of changes for reports since 2005: Site 3 added a column to each facility-specific report that provides comparative statistics for all mammography facilities in their local registry; Site 4 added a table that provides biopsy-yield for most recent data (2005 reports for Site 4 were based on data with a 365 day lag); Site 7 added data on cancer staging (minimal cancers and % of invasive node negative cancers).

^†Additional pathology reports are provided for cancer cases.

^‡Facilities can receive monthly reports by request and these reports only list positive mammograms and biopsy results for both positive mammogram and negative mammograms.

^§Yes=data is reported; No=data not reported;

^***if radiologist is inclined to calculate performance measure, data are available in the report to allow calculation.

^‖Performance definitions are based on American College of Radiology Breast Imaging Reporting and Data System (BI-RADS)³⁷
