Researchers have developed AnaDiffusion, a novel framework for generating 3D brain MRIs with enhanced anatomical control. Unlike previous methods that create entire volumes at once, AnaDiffusion breaks down the generation process by first training diffusion models for specific anatomical regions. These regional models are then assembled and refined to create a globally coherent brain MRI, allowing for controllable editing of specific parts without needing detailed segmentation maps during inference. This approach has demonstrated superior performance on the ADNI dataset, achieving lower FID scores and better accuracy in various brain regions. AI
