Current Challenges in the Use of Computed Tomography and MR Imaging in Suspected Cervical Spine Trauma

Abstract

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.
