Fast, high-sensitivity Rosette Spectroscopic Imaging (RSI) with Hadamard encoding is demonstrated in-vivo brain for four 10mm slices, 24x24 matrix, fov=240mm, 8-minute acquisition, with reduced gradient demands (maximum slew rate of 40mT/m/ms and maximum gradient readout of 5mT/m). Spectra for all voxels are processed and metabolites are quantified with an automated processing pipeline using LCModel.
