WebA total of 28 serial dilutions of nonionic (iohexol, 300 mg/mL) and ionic (iothalamate meglumine, 282 mg/mL) contrast media in saline and D5W were performed. Each sample contained a volume of 100 mL. For each combination of contrast media and fluid, volumetric mixture ratios of 1:1, 1:10, 1:50, 1:100, 1:200, 1:500, and 1:1000 were used.

The implications of these findings are discussed.

WebBackground Iothalamate and iohexol are contrast agents that have supplanted inulin for the measurement of glomerular filtration rate (GFR) in clinical practice. Previous studies have noted possible differences in renal handling of these 2 agents, but clarity about the differences has been lacking.
