New Delta-Diffusion model synthesizes longitudinal brain amyloid-PET data

Researchers have developed Delta-Diffusion, a new framework for synthesizing longitudinal brain amyloid-PET imaging data. This method uses a conditional Poisson Diffusion Bridge process, anchored to a subject's baseline PET scan, to model the temporal transition of amyloid accumulation. The framework incorporates a Diffusion Transformer with Poisson perturbation and adaptive modulation to account for clinical interval and structural MRI context, aiming to improve the tracking of disease progression.
