Routine pan-computed tomography (CT, including of the head, neck, chest, abdomen/pelvis) has been advocated for evaluation of patients with blunt trauma based on the belief that early detection of clinically occult injuries will improve outcomes. We sought to determine whether selective imaging could decrease scan use without missing clinically important injuries. ⋯ Selective scanning could reduce the number of scans, missing some injuries but few critical ones. The clinical importance of injuries missed on undesired scans was subject to individual interpretation, which varied substantially among authors. This difference of opinion serves as a microcosm of the larger debate on appropriate use of expensive medical technologies.
