Synopsis

Keywords: Pulse Sequence Design, Contrast Mechanisms, NeuroWe demonstrate sub-millimeter generalized Slice Dithered Enhanced Resolution (gSLIDER) for high-resolution spin-echo (SE) fMRI at 3T. Activations were significantly greater than standard SE fMRI, demonstrating the suitability of this method for high-resolution, mesoscale fMRI.
