The use of metrizamide for myelography.

Metrizamide (Amipaque; Winthrop) has provided consistently reliable diagnostic results in a small series of 150 myelograms. It is an acceptable diagnostic alternative to Dimer-X for myelography of the lumbar, thoracic and cervical segments. It is also safer but expensive, and its use requires modification of technique. The distressing headache which often follows lumbar puncture appears to be unavoidable.
