The role of early multislice computed tomography in major trauma

Abstract

Whole-body multislice spiral computed tomography (MSCT) has become a very important dignostic tool in the management of patients with multiple injuries. Many reports exist which demonstrate the feasibility and the benefit when using whole-body MSCT in the early phase of in-hospital management of trauma patients. Even in hemodynamically instable patients (except cardiac arrest), whole-body MSCT can be used and is a safe diagnostic procedure. While the diagnostic superiority of multislice computed tomography is proven for different organ regions (e.g. head/brain, chest, abdomen, pelvis and spine), its use as a single whole-body scan is still part of an ongoing discussion. Especially concerns about radiation exposure are the reason for uncertainty about when using whole-body trauma scan. Predefined scan protocols and individual positioning of patients may help to keep radiation dose as minimal as possible. To justify higher radiation dose, the indication must be chosen appropriately. Therefore, the use of a sensitive and specific triage scheme seems to be reasonable. Overscanning patients with minor trauma needs to be avoided, while the benefit for patients with severe multiple injuries is obvious.
