CT in an Emergency Setting

Computed tomography (CT) has become a central component in the imaging of both traumatic brain injury (TBI) and non-traumatic brain injury (nTBI) patients as it provides a key role in patient triage and management. Radiographers play a crucial role during imaging and must maintain an ongoing responsibility to ensure radiation safety during all CT procedures. However, CT imaging protocols used in TBI and nTBI patients remain unstandardized and may vary from department to department. Consequently, imaging techniques play an integral role in the diagnosis and management of patients presenting with TBI and nTBI and may influence life or death decisions. This chapter presents CT imaging techniques which include imaging algorithms and indications, CT protocols, and management of radiation dosages in the imaging of TBI and nTBI patients. This chapter aims to present examples of a few of many variations in current practice and to recommend what could be adopted to be standard protocols.
