  Functional changes in the apparent diffusion coefficient (ADC) were observed using an interleaved diffusion weighted sequence (b = 300 and 1570 sec/mm²) on a 4T MR system. The radial flashing checkerboard stimulus (8 Hz) elicited a mean ADC decrease of 3.29% in three subjects’ most significant voxel clusters. The observed results corroborate those seen in a recent study at 1.5T. Additional optimization of acquisition parameters and stimulation design is needed in future work to improve the utility of this method.
