Gadolinium-based contrast agents (GBCAs) are widely used in magnetic resonance imaging. Recently, a large amount of evidence indicates that change of magnetic resonance signal in deep brain nuclei is related to repeated injection of GBCAs. Especially in the dentatum and pallidum the gadolinium deposition is most obvious. This paper reviews the research status and policy progress of brain deposition of GBCAs, and introduces the relationship between gadolinium deposition in the brain and the type of GBCAs.
