• Dual phase
• Arterial phase
• Spleen
• Blunt trauma

Objective: To determine if the addition of an arterial phase abdominal computed tomography (CT) improves clinical outcomes in patients with blunt splenic injuries.
Methods: Retrospective review of patients who underwent CT of the abdomen revealing splenic injuries. Clinical management in these patients was determined.
Results: Fifty-one of three thousand five hundred twenty-five patients had splenic injuries. Twenty-five patients underwent nonsurgical management, and 3 failed. The theoretical additional arterial phase resulted in a 62% increase in mean effective dose compared to the portal venous phase alone.
Conclusions: Routine use of arterial phase CT in blunt trauma patients may not be warranted as there is minimal improvement in outcomes.
