Persistence of Gadolinium in CSF: A Diagnostic Pitfall in Patients with End-stage Renal Disease AJNR 22:1357-1361, Rai,A.T. &Hogg,J.P., 2001 See this aricle in Pubmed Article Abstract Two dialysis-dependent patients with end-stage renal disease underwent brain and spine MR imaging a few days after having undergone gadolinium-enhanced imaging studies. Increased signal intensity in the subarachnoid space on T1-weighted and fluid-attenuated inversion recovery images was noted. Excretion of gadolinium into the CSF was proven in one case by mass spectrometry. Dialysis-dependent patients with end-stage renal disease and neurologic abnormalities often undergo contrast-enhance d MR imaging. Recognition that these patients may show increased signal intensity in the subarachnoid space because of gadolinium excretion into CSF may prevent diagnostic errors.
