In this paper the basic steps of cost-effectiveness analysis (CEA) are applied in the evaluation of picture archiving and communication systems (PACS). The exercise demonstrates that evaluations of PACS have been technology-orientated, rather than problem-orientated. Moreover, many of the potential benefits of the system have been insufficiently investigated. Assessment based on the analysis of the bottlenecks in the film-based system alone appears to be quite inaccurate, as shown by the diverging outcomes of early assessment results. The development of PACS has reached a state in which the first clinical experiences are being collected. This provides an opportunity to test postulated costs and benefits. Moreover it may provide a better insight into the future potential of the technology. Experimenting with PACS is expensive. Hence, we should work together in evaluation, in order to benefit as much as possible from each other's experiences.
本文将成本效益分析（CEA）的基本步骤应用于图像存档与通信系统（PACS）的评估。该实践表明，对PACS的评估一直以技术为导向，而非以问题为导向。此外，该系统的许多潜在益处尚未得到充分研究。仅基于对基于胶片的系统中的瓶颈进行分析的评估似乎相当不准确，早期评估结果的不同就表明了这一点。PACS的发展已达到正在收集首批临床经验的阶段。这提供了一个检验假定成本和效益的机会。此外，这可能会让人更好地洞察该技术的未来潜力。对PACS进行试验成本高昂。因此，我们应该共同进行评估，以便尽可能多地从彼此的经验中受益。
