Expensive advanced imaging, such as magnetic resonance (MR) imaging, contributes to the unsustainable growth of health care costs in the United States. Evidence-based imaging decreases costs and improves outcomes by guiding appropriate utilization of imaging. Low back pain is an important case illustration. Despite strong evidence that early advanced imaging with MR imaging for uncomplicated low back pain leads to increased costs without significant clinical benefit, MR imaging utilization for acute low back pain has increased. Barriers to evidence-based imaging can be traced to patient- and physician-related factors. Radiologists have a critical role in addressing some of these barriers.
昂贵的高级影像学检查，如磁共振成像（MR 成像），是导致美国医疗保健成本不可持续增长的因素之一。基于证据的影像学检查可以通过指导影像学的合理应用来降低成本和改善结果。下腰痛就是一个很好的例子。尽管有强有力的证据表明，对于无并发症的下腰痛，早期进行 MR 成像等高级影像学检查会增加成本，但并没有显著的临床获益，但急性下腰痛的 MR 成像使用率仍在增加。基于证据的影像学检查的障碍可追溯到患者和医生相关的因素。放射科医生在解决其中一些障碍方面发挥着关键作用。
