MRI can provide superior soft tissue contrasts for radiation therapy planning. However,
radiation planning in the abdomen is especially difficult because respiratory motion can
cause misregistration across separate scans with different contrast weightings due to
inconsistent breath holds or poor patient compliance. While some studies have produced
volumetric and motion-resolved images, they are all limited to a single contrast which is
suboptimal for radiation planning. To address these issues, we present a free-breathing MR …
