Figure 2

Phantom experiments with varying H2O content, susceptibility and conductivity. Part one: phantom H2O content obtained from 2D-multi-echo GRE magnitude images using different RF bias correction methods: (a) SPM8 based RF bias correction (d) B1+ based RF correlation (g) correlation between RF bias correction methods; Part two: Phantom conductivity obtained from 2D and 3D multi-echo GRE phase images: (b) 2D method conductivity (e) 3D method conductivity (h) comparison between 2D and 3D method; Part three: phantom susceptibility calculated from 2D and 3D multi-echo GRE images: (c) 2D method susceptibility (f) 3D method susceptibility, i) correlation between 2D and 3D method. The length of the error bars represents twice the standard deviation of the parametric map in the ROI.
