The effect of intrathecal iohexol on visual evoked response latency: A comparison including incidence of headache with iopamidol and metrizamide in myeloradiculography

CNS-Effects from Subarachnoid Injections of Iohexol and the Non-Ionic Dimers Iodixanol and Iotrolan in the Rabbit

“…This has been demonstrated in comparative studies of iohexol and metrizamide using this animal model (7). These results predicted that using iohexol instead of metrizamide would lower the rate of minor side effects in myelography and this prediction has been confirmed in clinical comparative trials dealing with various aspects of adverse reactions during the last decade (2,3,6,9,14,16,17).…”

Adverse Reactions to Iopamidol and Iohexol Myelography with Special Attention to Headache: Role of Myelographic Technique

“…However, while the incidence of adverse reactions has indeed been reduced with the use of iopamidol and iohexol, even now up to 40 percent of patients have been reported to experience adverse reactions to myelography with either of these agents. 1,2 In order to further reduce patient discomfort following myelography, we attempted to identify risk factors which may have been associated with a higher incidence of side effects. Myelographic techniques, patient variables and post-myelographic symptoms were prospectively studied in a group of 152 patients undergoing iopamidol myelography, myelographic computed tomography (CT) or both, and in a second group of 28 patients undergoing similar studies with iohexol.…”
