J-resolved spectroscopy is a multidimensional technique to enhance spectral information by pushing multiplet splittings into a second dimension. EP-JRESI combines localized J-resolved spectroscopy with an echo planar readout for a single slice acquisition. Here, we extend EP-JRESI to include a 3D localization and use nonuniform sampling (NUS) and compressed sensing (CS) on the incrementally-acquired volume (ky, kz, t1) to achieve far greater accelerations in scan time.
