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. CONCLUSION The results of this study indicate that the accuracy of lesion size measurements in all magni...
