Researchers investigated multimodal fusion strategies for segmenting clinical PET/CT scans in prostate cancer patients, aiming to improve tumor burden estimation by combining PSMA and FDG tracers. They compared tracer-specific 3D nnU-Net baselines with early and intermediate fusion methods, including OEOD, OETD, and DECA-UNet architectures. While tracer-specific baselines performed well, fusion methods yielded mixed results, with FDG segmentation performance often degrading and no fusion strategy consistently outperforming the single-tracer baselines.

IMPACT This research highlights challenges in applying multimodal fusion for medical image analysis, suggesting that current architectures may not effectively preserve tracer-specific information, impacting the development of more accurate diagnostic tools.
