title: [Initial evaluation of thoracic injuries. Comparison of pulmonary radiography and x-ray computed tomography].
abstract: OBJECTIVE
  To investigate the contribution of computed tomography scan (CTS) to the initial évaluation of chest trauma.
  
  
  METHODS
  We carried out a two-year prospective study in all the chest trauma patients admitted to ICU. They underwent both Chest X-ray (CXR) and CTS within 24 jours of admission. CXR and CTS images were read by achieving a consensus between two radiologists who were unaware of the results of the other investigation. Then we compared these findings with the treatment received by the patients in the ICU.
  
  
  RESULTS
  From July 1, 1991 through July 1, 1993, 56 patients were included (21 with conventional CTS and 35 with helicoidal CTS). CTS demonstrated a significant number of pleural (p < 0.001), parenchymatous (p < 0.001), and mediastinal (p < 0.01) lesions that escaped detection on CXR (CTS+/CXR- lesions). Thoracic drainage was done in 16 patients because of abnormalities CTS+/CXR- (p < 0.01); six patients with CTS+/CXR- pulmonary contusions received Pressure Positive Ventilation (p < 0.01); and four CTS+/CXR- lesions were treated surgically (p < 0.05).
  
  
  CONCLUSIONS
  CTS adds significantly to the evaluation of chest trauma by allowing prompt, accurate assessment of lesions. In this study, over 50% of these lesions required specific treatment during the ICU stay.
