Representation-guided volumetric diffusion for label-free and slice-consistent 3D brain MRI synthesis

Existing methods for 3D brain MRI synthesis face a trade-off between efficiency, anatomical guidance, and volumetric coherence. Slice-wise or largely 2D diffusion pipelines are computationally efficient but can suffer from inter-slice inconsistency, whereas fully volumetric models better capture 3D structure at higher...
