摘要abstract
颈椎和胸腰椎损伤是创伤患者治疗中常见的问题，在急诊就诊的钝性创伤患者中，颈椎损伤发生率为3%~4%，胸腰段骨折发生率为4%至7%。颈椎血管损伤和胸腰椎损伤的筛查标准与颈椎损伤筛查标准相比，有效性和可接受性相对差。损伤模式和机制的复杂性使得决定什么时候进行影像检查和什么类型的检查具有挑战性。
于脊柱创伤的初始评估，CT优于X射线照片。CT血管造影和MR血管造影均可用于评估颈部血管损伤。评估脊柱创伤中的神经损伤时MRI优于CT脊髓造影。当担心韧带损伤或筛查反应迟钝患者颈椎不稳定时，MRI通常是合适的。

CT脊髓造影可用于评价椎间盘突出或硬膜外血肿所致的外伤性椎管狭窄，并可评估神经节前神经根是否狭窄。与常规CT一样，CT脊髓造影在评估脊髓挫伤、脊髓出血和神经节后神经根损伤方面不如MRI。
