Keywords: Motion Correction, Flow, ultra-high field
Motivation: The prolonged acquisition time and challenges in motion control for liver 4D flow imaging limit its clinical application.
Goal(s): To achieve free-breathing liver 4D flow imaging within clinically acceptable scan times utilizing retrospective motion correction.
Approach: Using a compressed sensing undersampling pattern to acquire imaging data, combined with adaptive data selection and motion-corrected reconstruction.
Results: The proposed method enhanced image quality and quantification accuracy, while reducing scan times to 6-8 minutes.
Impact: The proposed motion correction method improved image quality and quantification accuracy, while reducing scan times to a clinically acceptable 6–8 minutes.
