title: Lumbar myelography with iohexol and metrizamide. A double-blind clinical trial.
abstract: Two non-ionic contrast media, iohexol and metrizamide, were compared in a double-blind clinical trial which included 50 patients who underwent lumbar myelography for disc herniation or spinal stenosis. The frequency of adverse reactions was lower for iohexol which is recommended for extended trials and for examination of other compartments of the subarachnoid space.
