We read with interest the recent article by Langdorf et al,1 which reports the prevalence and importance of thoracic injury identified by chest computed tomography (CT) but not on chest radiography in blunt trauma. We agree with their assessment that there is a need for a validated decision instrument to support clinical judgment in identifying patients likely to benefit from CT.
