Prognostic value of quantitative MRI in chronic inflammatory neuropathies 119 7 Figure 7.3 Correlation matrix of quantitative parameters with clinical data per study group CIDP MMN Age Disease duration Time since last treatment ∆ FA ∆ RD ∆ MD ∆ AD ∆ T2 ∆ FF ∆ FA ∆ RD ∆ MD ∆ AD ∆ T2 ∆ FF Correlation matrix of the MRI metrics Δ FA, Δ MD, Δ AD, Δ RD, Δ T2 and Δ FF with the clinical covariates age, disease duration and time since last treatment, showed for patients with CIDP (left) and patients with MMN (right). Patients with CIDP had a moderate inverse correlation between Δ FA and disease duration ( r = -0.50, p = 0.02). Abbreviations: FA = fractional anisotropy; MD = mean diffusivity; AD = axial diffusivity; RD = radial diffusivity; T2 = T2 relaxation time; FF = fat fraction.
