Researchers have developed BrainNormalizer, a novel diffusion-based framework designed to reconstruct pseudo-healthy brain MRIs from scans containing tumors. This method utilizes an edge-guided ControlNet to learn anatomical priors and structural conditioning, enabling anatomy-informed reconstruction without requiring paired pre-tumor scans. By employing a deliberate misalignment strategy during inference, BrainNormalizer reconstructs subject-specific healthy brain anatomy that preserves individual structural characteristics, outperforming existing methods in distributional realism and structural consistency on the BraTS2020 dataset.
