xSPEN is a single-shot echo-planar imaging-based MRI approach with exceptional resilience to chemical shifts and field inhomogeneities. We introduce a time increasing (t1) evolution as chemical shift encoding to fast obtain multiple-voxel spectroscopy. The new method endows a 2D self-navigated motion correction and a unique J-decoupled spectrum by splitting the t1 evolution into τ-t1/2 and t1/2 on two sides of π pulse, which results a constant-τ J coupling evolution. We present in vitro results, demonstrating an alternative fast MRSI and increasing chemical shift separation and detection with the robustness to the in-plane motion and the unique J-decoupled spectrum capability.
