The study was noncomparative and involved 82 adult patients in four centers. Iohexol doses of 10-15 ml (180 mg I/ml) were administered and clinical and laboratory tests were performed before and at intervals during 48 hr after myelography. Side effects were noted in 29 (35%) of 82 patients. Spinal repuncture 6 or 24 hr after myelography was performed in 51 patients. No significant increases in cerebrospinal fluid parameters were seen. No seizures or spikes on electroencephalography were seen.
