in vivo Single-Scan 3D Spectroscopic Imaging by Spatiotemporal Encoding

Rita Schmidt¹, Lucio Frydman¹

Single-shot strategies foremost among them Echo Planar Spectroscopic Imaging alleviate the time constrain of the high dimensionality in the spectroscopic imaging. Although a powerful aid, EPSIs echo trains face limitations related the rapidly oscillating gradients. Among EPSIs alternatives is a recent proposal using spatiotemporal encoding (SPEN) principles. The acquired data in such experiment carries the spatial information, and its phase modulation that can convey the chemical shift offsets. The present study recover such additional chemical shift dimension using extended super resolution method that deals with the previous limitations and proves it in a in-vivo 7T animal and 3T human imaging.
