Comparison between two simulated results. (a)–(f): Simulated diffusion images in “homogeneous media”, where (a), (b), (c): C2 – C1 = 1.0, t = 20, 150, 270 min; (d), (e), (f): C2 – C1 = 0.6, t = 20, 150, 270 min; (a′)–(f′): simulated diffusion images in inhomogeneous media; (a″)–(f″) the concentration relative deviations of two kinds of simulations.
