Abstract
Magnetic resonance imaging has gained favor as the imaging modality of choice for evaluation of disc disease that affects the lumbar and thoracic spinal segments. This new noninvasive modality also competes favorably with myelography and CT for evaluation of cervical spine disc disease. An algorithmic approach to use of various imaging modalities for evaluation of suspected disc disease is provided in Figure 15. Important advantages of MR imaging relate to its multiplanar capability and unprecedented soft-tissue contrast for simultaneous evaluation of the thecal sac and spinal canal contents. These advantages often translate to more accurate and specific diagnoses related to degenerative disc disease.
