Computed radiography (CR) has provided a ready cost-effective transition from screen film to digital radiography and a convenient entrance to PACS. This article revisits artifacts encountered in CR systems. These artifacts may obscure abnormalities, mimic a clinical entity, or hamper image quality.
With the new-generation CR systems, software- and hardware-related artifacts have decreased, making operator errors more evident. The purpose of this study is to establish the current trend of CR artifacts and the new facets in identifying and resolving problems quickly that will help prevent future occurrences. This article also brings to light the importance of constant review required of this extensively studied topic to avoid diagnostic misadventures.
计算机放射摄影术（CR）为从屏-片系统向数字化放射摄影术的低成本有效转换提供了便利，并为 PACS 系统的使用提供了便利。本文回顾了 CR 系统中遇到的伪影。这些伪影可能会掩盖异常，模拟临床实体，或影响图像质量。
随着新一代 CR 系统的出现，软件和硬件相关的伪影减少了，操作人员的错误更加明显。本研究的目的是建立当前 CR 伪影的趋势，并快速识别和解决问题的新方面，以帮助防止未来再次发生。本文还强调了对这一广泛研究课题进行持续审查的重要性，以避免诊断失误。
