Reduced sensitivity to extracellular water at high b. (a) Ratio of Sextra/Sintra as a function of b demonstrating negligible contribution of the extracellular water signal to the total signal at b = 4000 s/mm2. This is true even when taking into account the predicted change in ADCextra due to changing extracellular space tortuosity λ with volume fraction α. (b) Theoretical and experimental λ vs. α plots (Reprinted with permission from Ref (20) Chen KC, and Nicholson C, PNAS 2000;97:8306-8311.) from which the high and low α curves were derived and plotted in (a).
