Iopamidol and metrizamide in cervical myelography: side effects, EEG, and CSF changes.
Two nonionic contrast media, iopamidol and metrizamide (Amipaque), were used for cervical myelography (C1-C2 puncture) in 95 consecutive patients. Both contrast media gave excellent radiographic results. Headache and vagal symptoms were similar in both groups, whereas metrizamide produced more electroencephalographic changes and epileptic seizures. Meningeal irritation occurred in both groups and was severe in three cases. Cerebrospinal fluid showed protein and cellular changes of inflammatory type in both groups. Iopamidol is considered to be the more suitable contrast medium for cervical myelography despite its slight neurotoxicity.
