Repeatability of simultaneous 3D ¹H MRF/²³Na MRI in brain at 7 T.

ABSTRACT: Proton MRI can provide detailed morphological images, but it reveals little information about cell homeostasis. On the other hand, sodium MRI can provide metabolic information but cannot resolve fine structures. The complementary nature of proton and sodium MRI raises the prospect of their combined use in a single experiment. In this work, we assessed the repeatability of normalized proton density (PD), T₁, T₂, and normalized sodium density-weighted quantification measured with simultaneous 3D ¹H MRF/²³Na MRI in the brain at 7 T, from ten healthy volunteers who were scanned three times each. The coefficients of variation (CV) and the intra-class correlation (ICC) were calculated for the mean and standard deviation (SD) of these 4 parameters in gr
