A Study to Learn How Gadoquatrane Moves Into, Through, and Out of the Body and How Safe it is in Children (From Birth to <18 Years), Who Will Undergo a Contrast Enhanced MRI (Quanti Pediatric)

摘要

Researchers are looking for a better way to help children under the age of 18 with any known or suspected problems scheduled for a "contrast-enhanced" Magnetic Resonance Imaging (MRI). MRI is used by doctors to create detailed images of the inside of the body to identify health problems. Sometimes doctors need to inject a contrast agent into a patient's vein to perform a "contrast-enhanced" MRI (CE-MRI). Such CE-MRI examinations may support doctors to identify certain health problems or improve their evaluation. The contrast agents commonly used in MRI are gadolinium-based contrast agents (GBCAs). GBCAs contain a "rare earth" element called gadolinium (Gd), which is needed for the increase in signal intensity and contrast in MRI. The gadolinium in these contrast agents is caged in a molecule (chelate complex). Researchers are developing new contrast agents with a lower amount of Gd needed per CE-MRI investigation. Gadoquatrane is one of these new contrast agents. It has been tested in several studies previously. The main purpose of this study is to learn how gadoquatrane moves into, through, and out of the body and how safe it is in children. The researchers will measure the amount

Area Under the Curve (AUC) of Gadoquatrane After Single Administration

Up to 8 hours post injection · (µmol Gd*h)/L

Plasma Clearance Normalized to Body Weight (CL/BW) of Gadoquatrane After Single Administration

Up to 8 hours post injection · L/(h*kg)

Apparent Volume of Distribution at Steady State Normalized to Body Weight (Vss/BW) of Gadoquatrane After Single Administration

Up to 8 hours post injection · L/kg
