title: [Value of double reading of whole body CT in polytrauma patients].
abstract: OBJECTIVE
  To assess the value of standard double reading of whole body CT in the management of polytrauma patients.
  
  
  METHODS
  Prospective study between January and July 2005. Two senior radiologists with expertise in trauma imaging, blinded to clinical findings, reviewed 105 initial CT examinations of polytrauma patients. These examinations had initially been interpreted by the on-call radiologist. The second interpretations were performed within 12 hours of admission, and were considered the gold standard.
  
  
  RESULTS
  A total of 105 patients were included with 82 males (78%) and 23 females (22%), aged between 2 and 83 years. The level of admission was graded III (n=64), II (n=30) and I (n=11). The second reading identified 3 lesions that were not initially described, each requiring a change in management, including splenic rupture (n=1), thoracic spine fracture (n=1) and epidural hematoma (n=1), with no unfavorable impact on mortality. Additional errors in the initial interpretation were identified: peripheral fractures (n=38), chest (n=36), brain (n=31), abdominal (n=28), spine (n=19) and maxillofacial (17) lesions and contrast extravasation (n=6).
  
  
  CONCLUSIONS
  Based on the large number and severity of some lesions missed at initial interpretation of whole body CT of polytrauma patients, we recommend standard double reading of these examinations.
