计算机断层扫描(CT)和磁共振成像(MRI)扫描的可用性迅速增长，但增加可用性的价值尚不清楚。我们记录了CT和MRI的可用性和使用之间的关系，并考虑了潜在的重要益处来源。我们讨论了如果要很好地理解价值，需要解决的关键问题。在我们研究的一个例子中，扩展成像可能是有价值的，因为它提供了更快地获得更准确的诊断信息，尽管改善健康结果的证据有限。这可能是一种常见的情况；因此，一个特别重要的问题是如何量化成像的非健康结果益处。[卫生事务27，第6期(2008年)：1467-1478；10.1377/hlthaff.27.6.1467]
The availability of computed tomography (CT) and magnetic resonance imaging (MRI) scanning has grown rapidly, but the value of increased availability is not clear. We document the relationship between CT and MRI availability and use, and we consider potentially important sources of benefits. We discuss key questions that need to be addressed if value is to be well understood. In an example we study, expanded imaging may be valuable because it provides quicker access to more precise diagnostic information, although evidence for improved health outcomes is limited. This may be a common situation; thus, a particularly important question is how non-health-outcome benefits of imaging can be quantified.
