In one dimensional (1D) spectroscopy, there is no information clearly linking J-coupled partners as there is with 2D localized correlated spectroscopy (L-COSY), which also produces much less crowded spectra. Recently, an echo planar spectroscopic imaging readout was added to L-COSY to collect a 4D data slice in (kx, ky, t2, t1) space (EP-COSI). Showing the potential for scan time reductions, NUS was retrospectively applied on the incrementally-acquired (ky, t1) plane. Here, we extend EP-COSI to a 3rd spatial dimension collecting data in (kx, ky, kz, t2, t1) and apply NUS prospectively on the (ky, kz, t1) volume.
