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.
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.
通过一个临床病例和美国放射学院乳腺摄影体模的测量，我们表明，一些数字乳腺摄影采集和图像显示组合会导致在几何放大图像上对病变大小的明显高估和低估。
本研究结果表明，在数字乳腺摄影中，所有放大模式下的病变大小测量准确性都应该是每个采集-显示系统组合的常规质量控制验收测试。
