Exploring Subnetwork Interactions in Heterogeneous Brain Network via Prior-Informed Graph Learning
Siyu Liu, Guangqi Wen, Peng Cao +4
Modeling the complex interactions among functional subnetworks is crucial for the diagnosis of mental disorders and the identification of functional pathways. However, learning the…
Multiscale Structure-Guided Latent Diffusion for Multimodal MRI Translation
Jianqiang Lin, Zhiqiang Shen, Peng Cao +3
Although diffusion models have achieved remarkable progress in multi-modal magnetic resonance imaging (MRI) translation tasks, existing methods still tend to suffer from anatomical…
BrainSCL: Subtype-Guided Contrastive Learning for Brain Disorder Diagnosis
Xiaolong Li, Guiliang Guo, Guangqi Wen +6
Mental disorder populations exhibit pronounced heterogeneity -- that is, the significant differences between samples -- poses a significant challenge to the definition of positive…
Visually-Guided Controllable Medical Image Generation via Fine-Grained Semantic Disentanglement
Xin Huang, Junjie Liang, Qingshan Hou +4
Medical image synthesis is crucial for alleviating data scarcity and privacy constraints. However, fine-tuning general text-to-image (T2I) models remains challenging, mainly due to…
BrainSTR: Spatio-Temporal Contrastive Learning for Interpretable Dynamic Brain Network Modeling
Guiliang Guo, Guangqi Wen, Lingwen Liu +6
Dynamic functional connectivity captures time-varying brain states for better neuropsychiatric diagnosis and spatio-temporal interpretability, i.e., identifying when discriminative…
Learning the Hierarchical Organization in Brain Network for Brain Disorder Diagnosis
Jingfeng Tang, Peng Cao, Guangqi Wen +3
Brain network analysis based on functional Magnetic Resonance Imaging (fMRI) is pivotal for diagnosing brain disorders. Existing approaches typically rely on predefined functional…
