Gadolinium Retention in the Brain: An MRI Relaxometry Study of Linear and Macrocyclic Gadolinium-Based Contrast Agents in Multiple Sclerosis

, 2019
BACKGROUND AND PURPOSE: Brain gadolinium retention is consistently reported for linear gadolinium-based contrast agents, while the results for macrocyclics are contradictory and potential clinical manifestations remain controversial.

Pharmaceutical and safety aspects of gadolinium-based contrast agents

, 2009
A contrast agent can substantially improve the diagnostic quality of magnetic resonance imaging. Gadolinium-based contrast agents are a very similar class of pharmaceuticals. But they differ in two important aspects, the complex stability and the ability

Synthesis and characterization of cationic gadolinium based MRI contrast agents

, 2006
During this project new macrocyclic gadolinium (Gd (III)) complexes with a cationic side group were made as potential contrast agents for magnetic resonance imaging (MRI). Two DO3A-derivates with a guanidine side group have been synthesized.
