Structural MRI Synthesis for Alzheimer's Disease via Conditional Diffusion on Anatomical Masks
arXiv:2606.18354v1 Announce Type: cross Abstract: Recent advances in generative machine learning models have significantly improved medical imaging, offering promising solutions for data augmentation, privacy preservation, and improved model generalization. However, synthesizing high-quality structural MRI data for Alzheimer's Disease (AD) remains challenging due to the subtle, region-specific, and progressive anatomical changes associated with neurodegeneration. In this paper, we extend the Med-DDPM conditional diffusion model -- originally designed for brain tumor synthesis -- to generate 3D
Advances in generative AI, particularly diffusion models, are rapidly extending their capabilities into complex scientific and medical domains, making high-quality synthetic data generation increasingly feasible.
This development could significantly accelerate Alzheimer's research and AI model development by overcoming data scarcity, privacy concerns, and enabling better generalization of diagnostic tools.
The ability to synthesize highly realistic and anatomically accurate structural MRI data for challenging conditions like Alzheimer's Disease opens new avenues for medical AI training and drug discovery, reducing reliance on limited real patient data.
