Gadolinium presence, MRI hyperintensities, and glucose uptake in the hypoperfused rat brain after repeated administrations of gadodiamide

Purpose The discussed topic about gadolinium-based contrast agents (GBCA) safety has recently been revived due to the evidence of hyperintensities observed in the dentate nucleus (DN) and globus pallidus (GP) in the brain of patients with normal kidney function. Several preclinical studies have been conducted to understanding how the use of GBCAs can promote the gadolinium deposition in the brain. Here, we evaluate the impact of chronic cerebral hypoperfusion on gadolinium presence.
