Description

Figures from article, "Variance components associated with long-echo-time MR spectroscopic imaging in human brain at 1.5T and 3T", accepted (December 2017) for publication in PlosONE. Figure 1 shows a brain slice and associated spectra. Figure 2 shows variance components of MRS (subjects, visit, scan, voxel, residuals) Authors: Michael J.

MRSI slice location and spectra. 1.5T MRSI volume of interest (yellow) overlaid on (a) sagittal localiser image and (b) axial T2W image. (c) and (d) show typical MRSI spectra acquired at 1.5T and 3T respectively with fitted spectra overlaid in red. The chemical shift is displayed relative to the water resonance frequency. (1.351Mb)

Metabolite signal variance components Variance components of the metabolite signal peak areas and peak area ratios at 1.5T (a) and 3T (b). To facilitate comparison between scanners and metabolites, the values shown are percentage CVs. (564.4Kb)
