SFL-Net: Source-Factorized Latent Representation Learning for Multi-Contrast MRI to Tau-PET Synthesis

arXiv:2602.22545v3 Announce Type: replace-cross Abstract: Tau positron emission tomography supports Alzheimer's disease staging but is difficult to scale because of tracer, scanner, and radiation constraints. Synthesis from structural MRI is therefore attractive, but it is a particularly difficult setting. T1-weighted and FLAIR MRI provide anatomy and disease correlated morphology, but they do not directly measure Tau-PET relevant signal. We introduce SFL-Net, a multi-input synthesis framework that predicts Tau-PET from T1-weighted and FLAIR MRI. SFL-Net factorizes the latent representation in
Advances in AI, particularly in generative models and deep learning, are enabling more sophisticated synthesis techniques from limited data sources, pushing the boundaries of medical image processing.
This development could significantly improve the accessibility and scalability of Alzheimer's disease diagnosis and staging, moving away from expensive and invasive methods like Tau-PET scans.
The ability to synthesize Tau-PET scans from more common MRI data could transform diagnostic workflows and democratize access to advanced neurological assessments, especially in regions with limited resources.

This method reduces the need for expensive and specialized Tau-PET scans for Alzheimer's diagnosis.
Improved and more accessible early diagnosis could lead to better management and treatment outcomes for Alzheimer's patients.
The development fosters a broader shift towards AI-driven synthesis and analysis in medical diagnostics, potentially extending to other difficult-to-acquire biomarkers.
