Comparative study of plasma clearance of iohexol at different injection doses.

Background: Our goal was to compare the metabolic curves of plasma clearance of iohexol (Cl) at standard dose (5 ml) and contrast-level dose (50 ml).

Methods: The concentration of iohexol was measured at fasting state and at nine different time periods after a single bolus of iohexol injection. The interval between the injection of the two doses was longer than 24 hrs.
