The application of spectroscopic imaging techniques such as CSI are limited in clinical practice mainly for the extensive acquisition times. Here we propose the use of a HighlY constrained backPRojection reconstruction (HYPR), a novel reconstruction technique for spectroscopic imaging with a radial trajectory to significantly reduce scan times. Simulations are presented that demonstrate good results for the obtained spectra and metabolite images, with a speedup factor of 17 over a fully sampled Cartesian acquisition.
