Whole-body computed tomography (CT) is becoming a mainstay of trauma imaging because it can help emergency department staff quickly and comprehensively evaluate the extent and severity of traumatic injuries. However, routine use of whole-body CT for trauma imaging remains controversial because of the lack of clear guidelines for appropriate use, concerns about how to manage incidental findings, and the risk posed by the modality's relatively high radiation doses. This article describes the pathobiology, epidemiology, and assessment of polytrauma and discusses the diagnostic evaluation of trauma with whole-body CT scanning.
全身计算机断层扫描（CT）正成为创伤成像的主要手段，因为它可以帮助急诊科工作人员快速、全面地评估创伤性损伤的范围和严重程度。然而，全身CT在创伤成像中的常规应用仍存在争议，原因包括缺乏关于适当使用的明确指南、对如何处理偶然发现的担忧以及该检查方式相对较高辐射剂量所带来的风险。本文描述了多发伤的病理生物学、流行病学和评估，并讨论了利用全身CT扫描对创伤进行的诊断评估。
