To optimize the diffusion-fMRI at different b-values by considering the signal performance compared with BOLD-fMRI during visual stimulation. The results show that the DfMRI at b-value = 1,200 s/mm2 should be a better choice than b-value = 600 and 1,800 s/mm2. DfMRI could provides the chance to approach the neuron activation than hemodynamic response.
