Periaortic hematoma on helical CT of the chest: a criterion for predicting blunt traumatic aortic rupture.
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.
