Radial echo planar spectroscopic imaging (REPSI) is applied in healthy prostate and compared to Cartesian EPSI acquisitions. Due to the small spatial extent of the anatomy-of-interest, REPSI is well-suited for acceleration in a reduced-field-of-view context. In this proof-of-concept study, we acquired both prospectively and retrospectively undersampled REPSI and Cartesian EPSI datasets in prostate phantom and in vivo, at multiple acceleration factors, and we compared both quantitative and qualitative results.
