Despite the clinical potential for Chemical Shift Imaging (CSI), its widespread applicability is limited by the severe spectral overlap in the one-dimensional spectra. Two-dimensional Magnetic Resonance Spectroscopy (2D MRS) has been proposed to alleviate complications due to spectral overlap, but suffers due to limited coverage. We propose the use of spin echoes to accelerate the already established Echo-Planar Correlated Spectroscopic Imaging (EPCOSI) technique. We show that the Multi-Echo based Echo Planar Correlated Spectroscopic Imaging (ME-EPCOSI) technique produces comparable 2D MRS spectra to the EPCOSI technique but in half the scan time without significant artifacts.
