Abstract

OBJECTIVE: Ferumoxytol, an ultrasmall superparamagnetic iron oxide particle, has been suggested as a potential alternative MRI contrast agent in patients with renal failure. We compared ferumoxytol to gadoteridol enhancement on T1- and T2-weighted MRI in CNS disorders to explore its diagnostic utility. SUBJECTS AND METHODS: Data were collected from three protocols in 70 adults who underwent alternate-day gadoteridol- and ferumoxytol-enhanced MRI using identical parameters. Two neuroradiologists measured lesion-enhancing size and intensity on contrast-enhanced T1-weighted images in consensus. T2-weighted images were evaluated for the presence of contrast-enhanced hypointensity. Mixed model repeated measures analysis of variance determined differences between T1-weighted enhancement size and intensity for individual protocols and group. RESULTS: After exclusions, 49 MRI studies in 29 men and 20 women (mean age, 51 years) were assessed. T1-weighted estimated enhancing sizes were different between agents (p = 0.0456) as a group; however, no differences were observed with untreated gliomas (n = 17) in two protocols (p = 1.0 and p = 0.99, respectively). Differences in T1-weighted enhancement intensity between agents were significant for the group overall (p = 0.0006); however, three-way interactions were not significant (p = 0.1233). T2-weighted images were assessed for contrast-enhanced hypointensity, observed in 26 of 49 (53%) ferumoxytol and zero of 49 (0%) gadoteridol scans. CONCLUSION: Ferumoxytol may be a useful MRI contrast agent in patients who are unable to receive gadolinium-based contrast agents. Greater experience with a wider variety of disorders is necessary to understand differences in enhancement with ferumoxytol compared with gadolinium-based contrast agents, given their different mechanisms of action.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
