Comparison of iohexol and meglumine-Na-Ca metrizoate in visceral angiography

Visceral angiography was performed in a double blind study in 54 patients using iohexol (350 mg I/ml) and meglumine-Na-Ca metrizoate (370 mg I/ml). No significant increase in serum values of either hepatic or pancreatic enzymes or electrolytes was registered. Both contrast media gave excellent demonstration of arteries as well as veins. Iohexol gave far less sensation of heat during the injections than metrizoate.
