(a) While the perfusion fraction Fp was not significantly different between thyroid and muscle tissue, the CSF, presumably through its physiological pulsation, showed a very high Fp. (b) The pseudodiffusion coefficient D* was relatively high in the thyroid and CSF with greater variability, when compared to the muscles. (c) Diffusion was nearly unrestricted in the CSF (high D), and less restricted in the loose thyroid parenchyma than in the tough muscle fibers (lowest D).
