The authors noted that there is increasing evidence that all agents (linear and macrocyclic) remain in human brain tissue for some period of time, where they may be taken up into various cell types, including glia and neurons. Gadolinium is widely employed as a contrast agent for magnetic resonance imaging (MRI) and has generally been considered to be safe. Absence of potential gadolinium toxicity symptoms following 22,897 gadoteric acid (Dotarem®) examinations, including 3,209 performed on renally insufficient individuals Eur Radiol . Gadolinium can stay in your system, causing symptoms like pain in the joints, hair loss, skin lesions, tinnitus, muscle weakness, balance problems and cognitive issues. NSF is a more severe and debilitating form of gadolinium toxicity that has been identified by health officials as a risk of individuals with kidney impairment. Toxicity is rarely associated with Gd due to its poor gastrointestinal absorption (it is suspected that very little Gd is absorbed from the gastrointestinal tract (<0.05%). To minimize this toxicity, gadolinium is administered in a chelated form with high kinetic stability so that under normal endogenous conditions, gadolinium dechelation would not usually occur. In these patients, gadolinium retention can cause a potentially fatal (and incurable) condition called nephrogenic systemic fibrosis, or … While gadolinium-based contrast agents (GBCAs) have long been recognized as critical components of MRI, the pharmacokinetics, pharmacodynamics and potential toxicity of these agents are under increasing scrutiny, particularly with reports that gadolinium can accumulate in the brain after contrast enhanced MRI examinations. A preclinical study by Bower et al. To reduce its toxicity, the gadolinium is administered with a chelating agent. They note that “the experimental evidence demonstrates that gadolinium-based contrast agents are biologically active – that is, not inert”. For the study, neurons modeling a subset of those in the basal ganglia were tested, because the basal ganglia region is one of two brain regions that displays the greatest T1-dependent signal hyperintensity changes.

For patients with pre-existing kidney failure, gadolinium dye may cause a condition known as nephrogenic systemic fibrosis (NSF), which affects the skin and internal organs. You can read the article and learn more about NCHR here – “For all agents, the magnitude of the toxicity increases with concentration.” (more…), A recently released review article by Drs. Gadolinium is one of the most abundant ”rare-earth” elements but is never found as a free element in nature. Multiple studies have shown that T1-signal intensity changes in the brain are the result of gadolinium deposition. While gadolinium-based contrast agents (GBCAs) have long been recognized as critical components of MRI, the pharmacokinetics, pharmacodynamics and potential toxicity of these agents are under increasing scrutiny, particularly with reports that gadolinium can accumulate in the brain after contrast enhanced MRI examinations. To keep the gadolinium from causing toxicity when used to enhance contrast in an MRI, it is attached to a large molecule, which may be called a chelate, ligand, or carrier. Most of the administered gadolinium chelate is excreted promptly through the urine, and the half-life (t1/2) of gadolinium in patients with normal kidney function is about 60 to 90 minutes. They do not accept funding from companies that make medical treatments. You can read the article and learn more about NCHR here – “The levels of gadolinium in the tumor and normal brain correlated suggesting a possible transit of gadolinium to the surroundings of the brain lesion.
