title: The role of 3D-CTA in the assessment of peripheral vascular lesions in trauma patients.
abstract: OBJECTIVE
  The goal of any imaging in the setting of a level 1 trauma center is to assess the injuries of a patient as fast as possible with the least amount of time spend to move the patients between rooms or scanners in order to reduce the time till final diagnosis. CT-angiography (CTA) has become increasingly used to analyze peripheral vascular lesions in blunt and penetrating trauma.
  
  
  METHODS
  Diagnostic angiography and CTA are competing methods for the display of peripheral vascular lesions. The specific advantages and shortcomings of both techniques for the routine use in a trauma center are discussed.
  
  
  RESULTS
  The inherent limitations of the spatial and temporal resolution of a CTA are compensated by the availability of the procedure and reduced time needed for the final diagnosis.
  
  
  CONCLUSIONS
  3D-CTA with multislice CT (MSCT) can be used to replace the diagnostic angiography in patients with blunt or penetrating extremity injuries.
