Evidence-based approach to use of MR imaging in acute spinal trauma

MR imaging directly shows integrity of spinal cord, and provides sensitive assessments of structurally important soft tissue investments of the vertebral column. High-resolution images should be acquired in at least two planes, with T1 and fluid sensitive sequences. In the acute and subacute settings, MR may be used to assess integrity of intervertebral discs prior to closed reduction of inter-facetal dislocations, to discriminate between neurological deficits due to intra-substance hemorrhage or edema, and to determine the status of spinal ligaments as an adjunct to 'clearing' the spine.
