Lumbar myelography.

The total material of lumbar myelographies performed with metrizamide (Amipaque) up to November 1976 (48,000 examinations) has been reviewed to assess the incidence of side-effects. A detailed analysis of 2,457 examinations from Ullevål Sykehus has been performed in order to assess adverse effects and diagnostic reliability. Three epileptic seizures were recorded, two of these in known epileptics. The rate of minor side-effects was low and the diagnostic accuracy high.
