UNASSIGNED: @entity1 presenting with @entity1109 may have a number of causative intradural and extradural etiologies, including @entity179 , spinal masses, @entity166 or inflammatory processes, vascular compromise, and @entity174 . @entity1 may present acutely or insidiously and may progress toward long-term paralysis if not treated promptly and effectively. Noncontrast CT is the most appropriate first examination in acute @entity130 cases to diagnose @entity174 as the cause of acute @entity602 . In most nontraumatic cases, MRI is the modality of choice to evaluate the location, severity, and causative etiology of @entity602 , and predicts which @entity1 may benefit from surgery. @entity602 from @entity612 and @entity27590 is best confirmed without MRI intravenous contrast. Many other myelopathic conditions are more easily visualized after contrast administration. Imaging performed should be limited to the appropriate spinal levels, based on history, physical examination, and clinical judgment. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals, and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.
