Use of computed tomography (CT) imaging for evaluation of the cervical spine following blunt trauma is both an efficient and reliable method for detecting injury. As a result, many trauma centers and emergency departments rely exclusively on CT scans to acutely clear the cervical spine of injury. Although quite sensitive for detecting bone injury, CT may be associated with a low sensitivity for detecting herniated discs, injured soft tissue or ligaments, and dynamic instability. In addition, CT-generated artifact may obscure pathological findings. In this case report, we describe the course of a patient whose CT scan harbored CT-generated artifact that suggested traumatic subluxation of the cervical spine. Clinicians should be aware of such artifact and how to recognize it when basing clinical management on such studies.
使用计算机断层扫描（CT）成像评估钝性创伤后的颈椎是一种检测损伤的高效且可靠的方法。因此，许多创伤中心和急诊科完全依赖CT扫描来急性排除颈椎损伤。尽管CT对检测骨损伤相当敏感，但对于检测椎间盘突出、软组织或韧带损伤以及动态不稳定可能敏感性较低。此外，CT产生的伪影可能会掩盖病理结果。在本病例报告中，我们描述了一名患者的病程，其CT扫描存在CT产生的伪影，提示颈椎创伤性半脱位。临床医生在基于此类研究进行临床管理时，应意识到此类伪影以及如何识别它。
