Lesion size inaccuracies in digital mammography.
OBJECTIVE
We show with both a clinical case and measurements using the American College of Radiology mammography phantom that some digital mammography acquisition and image display combinations lead to both marked over- and underestimation of lesion sizes on geometrically magnified images.


CONCLUSIONS
The results of this study indicate that the accuracy of lesion size measurements in all magnification modes should be a routine quality control acceptance test with each acquisition-display system combination in digital mammography.
