Advanced diagnostic imaging use is increasing, raising concerns about patient safety and cost.1 Recent estimates indicate that 4000 future cancers may result from the head computed tomographic (CT) examinations performed nationwide in 20072 and that costs of CT and magnetic resonance imaging (MRI) doubled between 1997 and 2006.3 In US emergency departments (EDs), the greatest increase has been in neuroimaging (head CT and MRI).4 Nevertheless, there are no national benchmarks against which health care providers and hospitals can measure their use of ED neuroimaging. We aimed to calculate head CT and MRI use in US EDs and to examine patient and hospital factors associated with use.
