Radiography: myelography

Introduction

  • Introduction of contrast into the subarachnoid space to allow visualization of the spinal cord.

Uses

  • Investigation of:
    • Back or neck pain.
    • Neurological deficits thought to arise from spinal cord compression.
  • Localization of site of compression if spinal surgery contemplated.

Advantages

  • Relatively accurate for diagnosis of spinal cord compression and localization of lesion.
  • May give some indication of likely etiology.

Disadvantages

  • Risk of exacerbating lesion.
  • Requires general anesthesia.
  • Invasive.
  • Contraindicated if increased CSF pressure or meningitis.
  • Risk of seizures after procedure.
