Radiology, as the field of expert image interpretation, has always been faced with questions about the trade-offs between the diagnostic quality of images and other issues related to the care of patients. Historically, image quality has been sacrificed somewhat to reduce the cost of imaging procedures or to reduce radiation exposure of patients, for example. More recently, in order to improve access to imaging information, radiology departments have begun to replace traditional film-based methods with digital techniques, which in some cases have reduced image quality. This again raises the question of how much diagnostic quality can be sacrificed to achieve a competing benefit for the patient (i.e., improved access to the image data).
放射学作为专业图像解读领域，一直面临着关于图像诊断质量与患者护理相关其他问题之间权衡的质疑。例如，从历史上看，为了降低成像检查成本或减少患者的辐射暴露，图像质量在一定程度上有所牺牲。最近，为了改善对成像信息的获取，放射科已开始用数字技术取代传统的基于胶片的方法，而在某些情况下这降低了图像质量。这再次引发了一个问题：为了给患者带来竞争优势（即改善对图像数据的获取），可以牺牲多少诊断质量。
