fMRI is one of the driving technologies of neuroscience. During the past years, acquisition speeds below one second per whole-brain volume have been achieved. The recently proposed 3D T-Hex Spiral trajectories provide a powerful approach to enable even faster fMRI. Here, we demonstrate the feasibility of fMRI at a sampling rate of 5Hz with these trajectories at 7T. We acquired whole-brain images of one subject performing a visuo-motor task in the scanner. Our results indicate high BOLD sensitivity and fidelity of voxel timeseries. In total, we analyzed 9000 volumes obtained during 30min of scanning.
