Synopsis

Keywords: Diffusion Reconstruction, Diffusion Reconstruction, Liver DWI, PROPELLER-EPI

Motivation: Routine free-breathing single-shot liver DWI is limited in geometric fidelity, spatial resolution and signal-to-noise ratio (SNR).

Goal(s): To enable high-quality free-breathing liver DWI using DW-PROPELLER-EPI.

Approach: A collaborative reconstruction framework for PROPELLER-EPI using POCUMUSE (CORPUSE), which incorporates field map constraints, was used to reconstruct the Free-Breathing liver DW-PROPELLER-EPI data.

Results: CORPUSE can enable distortion-free and high-resolution Free-Breathing liver DWI.

Impact: DW-PROPELLER-EPI with CORPUSE may benefit applications of liver DWI for challenging population.
