Delta-Diffusion: Modeling Longitudinal Brain Amyloid-PET Trajectories via Conditional Poisson Diffusion Bridge
Yongheng Sun, Minhui Yu, Mengqi Wu +2
While longitudinal brain PET imaging is the gold standard for quantifying the spatiotemporal accumulation of Beta-amyloid, its widespread clinical utility is constrained by high op…
RelA-Diffusion: Relativistic Adversarial Diffusion for Multi-Tracer PET Synthesis from Multi-Sequence MRI
Minhui Yu, Yongheng Sun, David S. Lalush +3
Multi-tracer positron emission tomography (PET) provides critical insights into diverse neuropathological processes such as tau accumulation, neuroinflammation, and -amyloid dep…
Unpaired Volumetric Harmonization of Brain MRI with Conditional Latent Diffusion
Mengqi Wu, Minhui Yu, Shuaiming Jing +3
Multi-site structural MRI is increasingly used in neuroimaging studies to diversify subject cohorts. However, combining MR images acquired from various sites/centers may introduce…
Functional Imaging Constrained Diffusion for Brain PET Synthesis from Structural MRI
Minhui Yu, Mengqi Wu, Ling Yue +2
Magnetic resonance imaging (MRI) and positron emission tomography (PET) are increasingly used in multimodal analysis of neurodegenerative disorders. While MRI is broadly utilized i…
