Contrast Media: Are There Differences in Nephrotoxicity among Contrast Media?

Table 1

Comparison of physical properties of commonly used iodinated contrast media.

	Concentration (mgl/mL)	Grams of iodine/100 mL	Osmolality (mmol/Kg at 37°C)	Viscosity (cP at 37°C)
Iodixanol (Visipaque)	270–320	27–32	290	6.3–11.8
Iohexol (Omnipaque)	140–350	14–35	322–844	1.5–10.4
Iopamidol (Isovue)	200–370	20–37	413–796	2.0–9.4
Iopromide (Ultravist)	150–370	15–37	328–774	1.5–10.0
Ioversol (Optiray)	160–350	16–35	355–792	1.9–9.0
