Partial correlation analyses of global diffusion tensor imaging-derived metrics in glioblastoma multiforme: Pilot study

Figure 1 Example of some sequences and diffusion tensor imaging maps from healthy brains (upper row) and brains with glioblastoma multiforme (lower row): T1-postgadolinium images (A and D), Flair sequence (B and E); pure isotropic diffusion (C), color map of the V1-vector (F).

Figure 2 Scatter matrix of the variable’s data grouped by diagnosis. A: Normal brains; B: Brains with GBM. MD: Mean diffusivity; FA: Fractional anisotropy; RA: Relative anisotropy; RD: Radial diffusivity; AD: Axial diffusivity; Cs: Spherical tensor; p: Pure isotropic diffusion; q: Pure anisotropic diffusion; L: Total magnitude of the diffusion tensor; Cl: Linear tensor; Cp: Planar tensor; GBM: Glioblastoma multiforme.

Figure 3 Graphs of the estimated marginal means for each tensor metric, the influence of age was controlled at the value of 43. 92 years. MD: Mean diffusivity; FA: Fractional anisotropy; RA: Relative anisotropy; RD: Radial diffusivity; AD: Axial diffusivity; p: Pure isotropic diffusion; q: Pure anisotropic diffusion; L: Total magnitude of the diffusion tensor; Cl: Linear tensor; Cp: Planar tensor; GBM: Glioblastoma multiforme.
