Small world properties of GM networks in the AD and NC using DKI metrics of MK, KFA, AK and RK. Both networks demonstrated small world architectures over a wide range of sparsity (6% ~ S ~ 40%) in comparison with the matched random networks. γ value was calculated by Cp/mean (Cprand), λ value was calculated by Lp/mean (Lprand). The small-worldness value of σ was presented by γ/λ
