Spine imaging.

Imaging of the vertebral column and spinal cord has evolved from plain film evaluation to computed tomography (CT), CT in conjunction with myelography, and most recently magnetic resonance imaging (MRI). Currently, MRI has essentially replaced other imaging modalities in evaluation of the spine because of its superiority in demonstrating anatomic detail and multiplanar capability. The following is a review of the various imaging modalities available and their application in the evaluation of common spinal disorders.
