Bland-Altman plots of the DSI-derived (a) and DTI-derived (b) diffusion properties and fiber-tracking metrics per muscle. The 95% confidence interval (limit of agreement) and the mean of the paired difference are indicated by dashed and solid blue lines, respectively. L-LPM, left lateral pterygoid muscle; R-LPM, right lateral pterygoid muscle; L-MM, left masseter muscle; R-MM, right masseter muscle; L-MPM, left medial pterygoid muscle; R-MPM, right medial pterygoid muscle; TN, track number; TML, track mean length; TV, track volume; FA, fractional anisotropy; MD, mean diffusivity; AD, axial diffusivity; RD, radial diffusivity; QA, quantitative anisotropy; DSI, diffusion spectral imaging; DTI, diffusion tensor imaging
