Iohexol versus metrizamide for cervical myelography: double-blind trial. 1985

S S Gebarski, and T O Gabrielsen, and J E Knake, and J T Latack, and P J Yang, and J T Hoff

Cervical myelography was performed by lateral C1-C2 puncture in 60 patients. Thirty patients received iohexol (an investigational aqueous contrast agent) and 30 received metrizamide in order to provide a prospective, randomized, double-blind trial comparing these contrast media. The two media produced radiographs of equal quality. Contrast-related morbidity was suffered by four patients (13%) in the iohexol group and by 11 patients (37%) in the metrizamide group. These features indicate that iohexol is superior to metrizamide as a contrast agent for cervical myelography.

UI MeSH Term Description Entries
D007463 Iodobenzoates Benzoic acid esters or salts substituted with one or more iodine atoms. Iodobenzoic Acids,Acids, Iodobenzoic
D007472 Iohexol An effective non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures. Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality. Compound 545,Exypaque,Iohexol 350,Nycodenz,Omnipaque

D008793 Metrizamide A solute for density gradient centrifugation offering higher maximum solution density without the problems of increased viscosity. It is also used as a resorbable, non-ionic contrast medium. Amipak,Amipaque
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
