Gadolinium chelates are extensively used in MRI studies. Neurotoxicity due to gadolinium chelates is minimal and uncommon. A 57-year-old woman in renal failure developed a subacute encephalopathy after inadvertent repetitive gadolinium contrast administration. An unusual MRI appearance with CSF hyperintensity due to gadolinium diffusion into the CSF is also shown.
钆螯合物广泛应用于磁共振成像（MRI）研究。钆螯合物所致的神经毒性极小且不常见。一名57岁的肾衰竭女性在无意中重复使用钆造影剂后出现了亚急性脑病。还展示了一种不寻常的MRI表现，即由于钆扩散到脑脊液中导致脑脊液信号增强。
