The object of this study was to compare of full-field digital mammography (FFDM) workstation and conventional picture archiving and communication systems (PACS) in image quality and diagnostic performance. We assembled 80 masses and 80 microcalcifications. Images were displayed on workstation, 5M, and 3M PACS monitors. The image quality for mammograms on workstation was significantly better than that for mammograms on PACS monitors. The sensitivity and NPV for microcalcifications on workstation were higher than those on PACS monitors. The conventional PACS cannot substitute for a FFDM workstation for mammographic evaluation.
本研究旨在比较全数字化乳腺摄影（FFDM）工作站和传统的影像归档和通信系统（PACS）在图像质量和诊断性能方面的差异。我们收集了 80 个肿块和 80 个微钙化。图像分别在工作站、5M 和 3M PACS 显示器上显示。工作站上的乳腺 X 线照片的图像质量明显优于 PACS 显示器上的乳腺 X 线照片。工作站上微钙化的敏感性和阴性预测值（NPV）高于 PACS 显示器上的微钙化。传统的 PACS 不能替代 FFDM 工作站进行乳腺 X 线摄影评估。
