FINDINGS:
The cardiac, mediastinal and hilar contours appear unchanged.  The
 heart appears mildly enlarged.  There is slight unfolding of the thoracic
 aorta.  The lungs appear clear.  There are no pleural effusions or
 pneumothorax.  Mild relative elevation of the right hemidiaphragm is similar. 
 Although this study does not include a dedicated rib series, no fracture is
 identified.

IMPRESSION:
No definite evidence of injury.
