A Prior-information-guided Residual Diffusion Model for Multi-modal PET Synthesis from MRI

Zaixin Ou, Caiwen Jiang, Yongsheng Pan, Yuanwang Zhang, Zhiming Cui, Dinggang Shen

IJCAI 2024poster

Alzheimer's disease (AD) leads to abnormalities in various biomarkers (i.e., amyloid-β and tau proteins), which makes PET imaging (which can detect these biomarkers) essential in AD diagnosis. However, the high radiation risk of PET imaging limits its scanning number within a short period, presentin…

Synthesizing Aβ-Pet Via An Image And Label Conditioning Latent Diffusion Model For Detecting Amyloid Status

Zaixin Ou, Yongsheng Pan, Yuanning Li, Fang Xie, Qihao Guo, Dinggang Shen

ICASSP 2024accepted

Deposition of β-amyloid is a crucial biomarker to evaluate subjects with early-onset dementia, often evaluated through Aβ-PET imaging. Aβ-PET is expensive and radiation-heavy; thus, it’s advisable to avoid it unless medically necessary. Therefore there is a compelling need to classify Aβ and detect…
