There is controversy regarding the optimal imaging strategy in adult blunt trauma patients for suspected cervical spine trauma. Some investigators recommend negative computed tomography (CT) alone to clear the cervical spine in adult blunt trauma patients, while others insist that MR imaging is necessary, especially among obtunded adult blunt trauma patients. CT is an excellent imaging modality for bony cervical spine injury; however, there is a nonzero rate of clinically significant cervical spine injuries missed on CT. MR imaging has high sensitivity for soft tissue cervical spine injuries, but low specificity for the rare isolated unstable ligamentous cervical spine injury.
对于疑似颈椎创伤的成年钝性创伤患者，最佳成像策略存在争议。一些研究者建议仅通过计算机断层扫描（CT）阴性结果来排除成年钝性创伤患者的颈椎损伤，而另一些人则坚持认为磁共振成像（MR）是必要的，尤其是在意识不清的成年钝性创伤患者中。CT是诊断颈椎骨损伤的一种优秀成像方式；然而，CT漏诊具有临床意义的颈椎损伤的概率并非为零。MR成像对颈椎软组织损伤具有高敏感性，但对罕见的孤立性不稳定颈椎韧带损伤的特异性较低。
