Excretory Urography A Comparison of Iopamidol and Meglumine Diatrizoate

William Moreau Thompson

Abstract

This article reviews the physiologic and clinical aspects of intravenous unographic contrast agents and discusses adverse reactions. The ionic agent meglumine diatrizoate and the nonionic agent iopamidol are compared. The results of some clinical trials and experimental studies have shown that iopamidol is a better contrast agent for excretory urography than ionic agents. More extensive clinical trials are needed to verify these results.
