title: Periaortic hematoma on helical CT of the chest: a criterion for predicting blunt traumatic aortic rupture.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the accuracy of helical CT of the chest for predicting blunt traumatic aortic ruptures when periaortic hematoma is used as a positive criterion.
  
  
  CONCLUSIONS
  We recommend the use of periaortic hematoma as a criterion for predicting traumatic aortic ruptures on CT because this criterion is sensitive and can reduce the false-positive rate of CT interpretations.
