DisQ-HNet: A Disentangled Quantized Half-UNet for Interpretable Multimodal Image Synthesis Applications to Tau-PET Synthesis from T1 and FLAIR MRI

Researchers developed DisQ-HNet, a new AI framework that synthesizes tau-PET brain scans from MRI data to detect Alzheimer's disease pathology. The method uses advanced neural network architectures to generate cost-effective alternatives to expensive PET imaging while maintaining diagnostic accuracy.

Latent 3D Brain MRI Counterfactual

Researchers developed a two-stage method using Structural Causal Models in latent space to generate high-quality 3D brain MRI counterfactuals, addressing the challenge of limited training data in medical imaging. The approach combines VQ-VAE encoding with causal modeling to produce diverse, high-fidelity brain MRI data beyond the original training distribution.
