In this project, we developed improved sampling and reconstruction strategies to provide finer temporal resolution for hyperpolarized carbon-13 3D time-resolved MRSI with compressed sensing and multiband excitation pulses. These improved compressed sensing strategies better exploit the temporal redundancy. Results are shown with a 32-fold acceleration for a 2 sec temporal resolution, 3D dynamic MRSI acquisition.
