Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated contrast agent that attenuates X-rays, enhancing vascular and tissue contrast during imaging.
Radiopaque agent: iodine-containing contrast medium that attenuates X-rays, enhancing vascular and tissue contrast during imaging. Non-ionic, low-osmolar agent.
Intravenous: 0.5-1.0 mL/kg (20-43 mg I/kg) for CT; intra-arterial: 5-15 mL for selective studies; maximum single dose 150 mL.
1-2 mL/kg IV up to 150 mL for CT; 30-50 mL IV for DSA; max 350 mL per procedure.

2 hours (normal renal function); prolonged to 20-40 hours in severe renal impairment (CrCl <10 mL/min).
Terminal elimination half-life is approximately 1.5–2 hours in patients with normal renal function. May be prolonged in renal impairment.
Renal: >90% via glomerular filtration; unchanged drug. Biliary: <1%. Fecal: negligible.
Primarily renal excretion via glomerular filtration; >95% eliminated unchanged in urine within 24 hours. Biliary/fecal excretion is negligible (<1%).
