Intra-individual comparison of average glandular dose of two digital mammography units using different anode/filter combinations.

Rationale And Objectives: The aim of this study was to compare average glandular dose (AGD) in two full-field digital mammography units using different anode/filter combinations.

Materials And Methods: Mammographies of 50 consecutive patients on a mammography system using a tungsten/rhodium (W/Rh) anode/filter combination were retrospectively compared to prior examinations on a different mammography unit using combinations of Molybdenum (Mo) and Rhodium (Rh). To exclude effects of increasing patient age, two prior examinations within 5 years were used.
