Existing preoperative imaging models often rely on radiologist-defined variables, contrast-enhanced imaging, or manual annotations. We propose an anatomy-privileged teacher--student framework for patient-level PNI prediction from T2-weighted MRI. During training, the teacher uses MRI with tumor and liver masks to learn dense token routing, and the student distills this guidance to retain and aggregate informative tokens under a fixed budget. Anatomical supervision is restricted to training, and the deployed model does not require masks at inference. In 155 patients, the proposed method achieved the highest mean AUROC of 0.750 among matched MRI-only baselines evaluated under the same protocol, with 1.43 GFLOPs and 8.02 ms per case on a Jetson Orin Nano Super Developer Kit.", "url": "https://wpnews.pro/news/anatomy-privileged-distillation-with-token-routing-for-mri-based-prediction-of", "canonical_source": "https://arxiv.org/abs/2607.11987", "published_at": "2026-07-15 04:00:00+00:00", "updated_at": "2026-07-15 04:01:05.633978+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "computer-vision"], "entities": ["Jetson Orin Nano Super Developer Kit"], "alternates": {"html": "https://wpnews.pro/news/anatomy-privileged-distillation-with-token-routing-for-mri-based-prediction-of", "markdown": "https://wpnews.pro/news/anatomy-privileged-distillation-with-token-routing-for-mri-based-prediction-of.md", "text": "https://wpnews.pro/news/anatomy-privileged-distillation-with-token-routing-for-mri-based-prediction-of.txt", "jsonld": "https://wpnews.pro/news/anatomy-privileged-distillation-with-token-routing-for-mri-based-prediction-of.jsonld"}}
