Delta-Diffusion framework models brain amyloid-PET trajectories using conditional diffusion

Researchers have developed Delta-Diffusion, a new framework for modeling longitudinal brain amyloid-PET trajectories. This method uses a conditional Poisson Diffusion Bridge process, anchored to a subject's baseline PET scan, to generate synthetic longitudinal images. The framework incorporates a Diffusion Transformer with adaptive modulation to account for elapsed time and structural MRI context, aiming to improve the tracking of disease progression. AI

IMPACT This research offers a novel computational framework for tracking disease progression in brain amyloid-PET imaging, potentially improving diagnostic and prognostic capabilities.
