Abstract：
:This article emphasizes the technical aspects of MR imaging in acute cervical trauma, and details the specific protocols used at the authors' institution. A systematic approach to the evaluation of MR images in the trauma setting is discussed, and the role of MR imaging in the characterization of spinal cord injury and identification of spinal instability is defined. Correlations between MR imaging findings and patient functionality and outcome are outlined, and various classifications of cervical spine injuries are reviewed.
