The purpose of the study was to determine the role of magnetic resonance imaging (MRI) in intubated multitrauma patients with normal computed tomography (CT) in excluding unstable ligamentous injury to the cervical spine. A retrospective evaluation was done on those multitrauma patients admitted to the intensive care unit of a level 1 trauma centre who had normal single-slice helical CT cervical spine and underwent MRI for cervical spine clearance from 1/1/04 to 30/6/05. Fifty-five patients met the inclusion criteria. Ten of these patients had a discoligamentous injury identified on MRI; however, all these patients had injuries limited to only one of the three columns of the cervical spine. Single-slice helical CT with sagittal reformats had a negative predictive value of 82% for discoligamentous injury and 100% for unstable injury. A normal single-slice helical CT with sagittal reformats of the cervical spine in intubated trauma patients excluded unstable injuries at follow-up cervical spine MR imaging.
本研究的目的是确定磁共振成像（MRI）在计算机断层扫描（CT）正常的插管多发伤患者中排除颈椎不稳定韧带损伤的作用。对入住一级创伤中心重症监护病房的多发伤患者进行了回顾性评估，这些患者颈椎单排螺旋CT正常，并在2004年1月1日至2005年6月30日期间接受了颈椎MRI检查以排除颈椎损伤。55例患者符合纳入标准。其中10例患者在MRI上发现了椎间盘韧带损伤；然而，所有这些患者的损伤仅限于颈椎三柱中的一柱。带有矢状面重建的单排螺旋CT对椎间盘韧带损伤的阴性预测值为82%，对不稳定损伤的阴性预测值为100%。插管创伤患者颈椎矢状面重建的单排螺旋CT正常可排除后续颈椎MRI检查中的不稳定损伤。
