Kinetics of Urinary Excretion of Gadolinium Contrast Agents Used in MRI Examinations
Recruiting now · Not applicable
Conditions studied: Magnetic Resonance Imaging
In brief
This is a single-center cohort study aimed to describe the urinary excretion kinetics of gadolinium contrast agents (Gd-CAs). Patients with a prescription for injected MRI are invited to participate in the study. If they agree, blood and urine samples are collected before Gd-CAs injection, and urine samples are collected between 0- and two-and-a-half-hours post-injection of Gd-CAs.
