Noise-Aware Boundary-Enhanced Generative Learning for Ultrasound Speckle Reduction
Yuexi Gu, Mengqi Wu, Yongheng Sun +3
Ultrasound is a non-invasive, real-time, and cost-effective imaging technique widely used in clinical diagnosis. However, its diagnostic efficacy is often compromised by inherent s…
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…
Unified Multi-Site Multi-Sequence Brain MRI Harmonization Enriched by Biomedical Semantic Style
Mengqi Wu, Yongheng Sun, Qianqian Wang +2
Aggregating multi-site brain MRI data can enhance deep learning model training, but also introduces non-biological heterogeneity caused by site-specific variations (e.g., differenc…
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…
Iterative Learning for Joint Image Denoising and Motion Artifact Correction of 3D Brain MRI
Lintao Zhang, Mengqi Wu, Lihong Wang +3
Image noise and motion artifacts greatly affect the quality of brain MRI and negatively influence downstream medical image analysis. Previous studies often focus on 2D methods that…
Disentangled Latent Energy-Based Style Translation: An Image-Level Structural MRI Harmonization Framework
Mengqi Wu, Lintao Zhang, Pew-Thian Yap +2
Brain magnetic resonance imaging (MRI) has been extensively employed across clinical and research fields, but often exhibits sensitivity to site effects arising from non-biological…
