  • Title: Iohexol versus metrizamide for lumbar myelography: double-blind trial.
    Author: Gabrielsen TO, Gebarski SS, Knake JE, Latack JT, Yang PJ, Hoff JT.
    Journal: AJR Am J Roentgenol; 1984 May; 142(5):1047-9. PubMed ID: 6372410.
    Abstract:
    Lumbar myelography was performed in 50 patients; 25 received iohexol (an investigational aqueous contrast agent) and 25 received metrizamide. The two media produced radiographs of equal quality. However, iohexol is stable in solution, while metrizamide is not. Further, markedly less morbidity resulted from iohexol. These features indicate that iohexol may be superior to metrizamide as a contrast agent for lumbar myelography.
