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

Agamdeep S. Chopra, Caitlin Neher, Hesamoddin Jahanian, Juampablo E. Heras Rivera, Mehmet Kurt, Tianyi Ren

A disentangled quantized Half-UNet generates tau-PET images from T1-weighted and FLAIR MRI with top fidelity and Braak-stage accuracy.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Across 17 evaluated models, the proposed DQ2H-MSE-Inf variant achieved the best raw PET fidelity and the strongest downstream Braak-stage performance, while remaining competitive on SUVR reconstruction and regional agreement.

C2weakest assumption

That the partial information decomposition components remain clinically meaningful and that the synthesized tau-PET does not introduce artifacts that would alter Braak staging or regional uptake interpretation in real patients.

C3one line summary

A Partial Information Decomposition-guided disentangled quantized Half-UNet synthesizes tau-PET from multimodal MRI and outperforms baselines on raw fidelity and Braak-stage tracking in ADNI-3 and OASIS-3 data.
