In this pilot study, we implement a radial echo-planar spectroscopic imaging (rEPSI) sequence and compare its performance to the Cartesian (EPSI) sequence under multiple rates of retrospective undersampling, for the case of 2D acquisitions in which a single phase-encoded direction is undersampled for EPSI, and a reduced number of radial profiles using golden angle view ordering are reconstructed for rEPSI. Fully sampled data from a healthy volunteer brain and from a brain phantom are acquired. The retrospectively undersampled data is reconstructed using compressed sensing with Total Variation regularization, and the performance of both methods are compared.
