Myelography using iohexol (Omnipaque).

Abstract

Myelography was performed in 30 patients using iohexol (Omnipaque) 240 mg I/ml for lateral C1C2 injections, or iohexol 300 mg I/ml for lumbar injections. The dose varied from 3 to 10 ml. The patients were observed for 48 h for possible adverse reactions. A complete neurological examination was repeated 24h after the investigation, and EEG recordings 3-24h after the investigation. Adverse reactions occurred in 4 patients, minor EEG changes occurred in 1 patient, and slight changes in the neurological status were seen in 2 patients.
