ABSTRACT
Gadolinium-based contrast agents are used across species to better visualize abnormalities during MRI and are considered generally safe in clinical practice. The aim of this study was to investigate central nervous system (CNS) gadolinium deposition in 11 dogs that had an MRI performed, received 0.22 mL/kg (0.1 mmol/kg) of gadopentetate dimeglumine, and were necropsied on the same hospital admission. The index case was a 5-year-old castrated male Australian Shepherd that presented for ataxia and following MRI developed seizure-like activity that became refractory to anticonvulsant therapy. Gadolinium concentration was quantified in CNS tissues by inductively-coupled plasma mass spectrometry and was 43-fold higher in the index case. These findings suggest the possibility of gadolinium toxicity in select patients.
