A chained diffusion refinement network reconstructs free-breathing liver 4D MRI from retrospectively undersampled radial data and reports higher PSNR/SSIM than compressed sensing and Re-Con-GAN across 3x to 30x acceleration, with 11-second inference per volume.

Rapid Reconstruction of Extremely Accelerated Liver 4D MRI via Chained Iterative Refinement
A chained diffusion refinement network reconstructs free-breathing liver 4D MRI from retrospectively undersampled radial data and reports higher PSNR/SSIM than compressed sensing and Re-Con-GAN across 3x to 30x acceleration, with 11-second inference per volume.
