xSPEN is a new single-shot imaging approach with exceptional resilience to field heterogeneities: its images do not suffer from miss-registrations, require a priori information nor use post-acquisition corrections, to deliver faithfully the spins’ spatial distribution. xSPEN, however, suffers from SNR penalties due to its non-Fourier nature and its considerable diffusion losses –especially when desiring high resolution. This study introduces partial Fourier transform approaches that acting along either the readout or the spatiotemporally-encoded dimensions, reduce both of these penalties. The principles of these partial FT methods are given, and applications in materials, preclinical and human single-shot xSPEN imaging are presented.
