Iterative Navigator-Based Retrospective Motion Correction for Multi-Shot Brain MR Elastography and Evaluation of Single-Shot Post-Reconstruction Correction.
PURPOSE Brain MR elastography (MRE) is uniquely sensitive to subject motion, as even small phase deviations can produce large errors in the mechanical properties estimated. Existing motion correction strategies have not been validated for MRE and are often incompatible with complex multi-shot or joint temporal reconstr...
