Figure 1.

Examples of IVIM data fitted with the bi-, mono-exponential and Kennan models. Typical IVIM signal, for one animal, resulting from the subtraction of the diffusion component from the total MRI signal versus b-value for Δ = 24 ms. The black circles represent the experimental data. The black, blue, and red lines correspond to the three fitting models, the bi-, mono-exponential and Kennan models, respectively. The ROI masks are given in the upper right corners: (a, b) LC, (c, d) LT. The curves were fit to the data with b-values ranging from 0 to 500 s/mm². Error bars represent SD. Scale bar: 5 mm.
