Researchers have developed ProgFormer, a novel hierarchical voxel-space Diffusion Transformer designed for predicting future brain MRI scans. This model addresses the challenge of subtle longitudinal changes by employing a dual-pathway approach: a coarse pathway models overall brain structure and longitudinal context, while a fine pathway refines voxel-level details. ProgFormer operates directly in voxel space, avoiding information loss from latent-space compression and enabling end-to-end prediction through conditional flow matching. Experiments on ADNI, AIBL, and OASIS benchmarks show favorable performance compared to existing state-of-the-art methods. AI
