Clinical experience with iopamidol for myelography.
Within 20 months 145 ascending thoracocervical myelographies and 155 lumbar myelographies with the nonionic water-soluble contrast medium iopamidol were performed. The iodine concentration given was 250 mg I/ml or 200 mg I/ml respectively. The total iodine never exceeded 2.5 g (8-10 ml). Image quality was assessed in terms of diagnostic value having experience of more than 1,000 myelographies using metrizamide. Picture quality was similar to metrizamide of equal iodine concentration. In 35 patients electroencephalography (EEG) was recorded before and after myelography with iopamidol 250. No changes that could be referred to the contrast medium were seen. There were no adverse reactions to lumbar myelography other than those following the lumbar puncture. In thoracocervical myelography mild and transient side effects occurred in 41 (28.3%). The most common were headache (41 cases), nausea (12), radicular pain (10), and dizziness (five). General seizures and psychopathologic symptoms were not observed.
