Relationship between muscle fat fraction measured by MRI and MRS in all groups and muscles using (a) a single peak model (y=0.74×−0.02, R2=0.93), or (b) a multi-peak (8-peak) model (y=0.96×+0.01, R2=0.98) for fat spectral decomposition. MRS determined fat fractions were determined based using a model independent method (peak integration in a and b) and using a 8 peak fat-water model in AMARES (y=0.93×+0.02, R2=0.98) (c). The dashed line represents the identity line. The corresponding Bland-Altman plots are shown to the right of each relationship.
