In the past, CT scanners were located in the radiology department, frequently even on another floor than the emergency department (ED) were the trauma patient is admitted. The past assumption that TBCT in severely injured trauma patients is too time consuming may no longer be held, since an increasing number of trauma centers have a CT scanner available at the ED or even in the trauma room itself. Several studies evaluated time intervals associated with TBCT usage in severely injured patients. Although these studies are incomparable with respect to design, CT scanners used, diagnostic work-up protocols and trauma populations, the main conclusion is clear. TBCT scanning in trauma patients is not as time consuming as was once expected and may even be time saving compared to conventional imaging protocols supplemented with selective CT.
