Abstract

Morbidity and mortality related to trauma patients has decreased significantly over the past several decades due to the advent of various protocols such as Advanced Trauma Life Support (ATLS) guidelines, point of care (POC) ultrasonography, and pelvic stabilization. Many patients with blunt, suspected polytrauma, receive whole body computed tomography (WBCT) as an initial screening to identify injuries. There is controversy surrounding this as computed tomography (CT) has varying sensitivity despite great specificity and exposes the patient to large amounts of radiation that may be unnecessary. Recent advances in CT scanner software allow for better imaging processing while at the same time reducing the radiation dosage. The objective of this study was to assess if low dose WBCT could be used as an initial screening tool for blunt polytrauma, without increasing the risk of missed injuries compared to standard dose WBCT.
