We show that some combinations of digital mammography acquisition and display systems can lead to clinically significant over- or underestimation of lesion size in magnification mode. This phenomenon can occur even with acquisition and display systems from the same manufacturer. Thus, the accuracy of lesion size in each magnification mode should be a routine QC acceptance test performed on each digital mammography acquisition–display system combination
