BrainNormalizer reconstructs pseudo-healthy brain MRIs using diffusion models

By PulseAugur Editorial · [1 sources] ·

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. AI

IMPACT This method could improve the analysis of brain tumors by providing a clearer reference for tumor-induced deformations.

    BrainNormalizer: Anatomy-Informed Pseudo-Healthy Brain Reconstruction from Tumor MRI via Edge-Guided ControlNet

    arXiv:2511.12853v2 Announce Type: replace-cross Abstract: Brain tumors induce complex structural deformations that obscure the patient' s original neuroanatomy, making it difficult to distinguish tumor-induced changes from inherent anatomical variability. Reconstructing a subject…
