The review article describes individual MR contrast agents on the basis of gadolinium chelates, it focuses on their physic-chemical properties and clinical use. The paper emphasizes schematic division of the contrast agents to linear and cyclic chelates because the situation in vivo is more complex. The paper focuses further on nephrogenic systemic fibrosis in relation to the use of several specific linear contrast agents. Regarding gadolinium retention in the brain the paper describes current level of knowledge where visible changes are present in the areas of high concentrations of metalloprotein ferritin. The same contrast agents related to nephrogenic systemic fibrosis also cause the most pronounced retention. However, even in this topic the situation is more complex. No convincing neurological symptomatology has been attributed with this retention and no histopathological changes were found in animal models after applications of significantly higher amounts of contrast agents. Finally, current legislative steps of regulation authorities in individual countries are described with the emphasis that these steps are inconsistent. Brief description of off-label use is described according to the current legislation.
