February 24, 2019 – Researchers from Finland, led by Dr. Aida Kiviniemi, found that gadolinium deposits can be detected in both enhancing and non-enhancing gliomas, adjacent normal brain tissue, and necrosis. The authors said that to their knowledge, “this is the first study to provide quantitative data of gadolinium retention in gliomas and neighboring normal brain with respect to tumor enhancement and type of GBCA used”. “The levels of gadolinium in the tumor and normal brain correlated suggesting a possible transit of gadolinium to the surroundings of the brain lesion. The most powerful predictor of gadolinium retention was the type of GBCA administered with significantly higher gadolinium accumulation detected with linear (gadodiamide and gadopentetate dimeglumine) relative to macrocyclic (gadoterate meglumine and gadobutrol) agents.” The study, Gadolinium retention in gliomas and adjacent normal brain tissue: association with tumor contrast enhancement and linear/macrocyclic agents, was recently published online in Neuroradiology.
