New AI framework predicts cancer invasion risk from MRI scans

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel Order-Aware Slab Multiple Instance Learning (OAS-MIL) framework to predict the risk of perineural invasion (PNI) in intrahepatic cholangiocarcinoma (ICC) using preoperative MRI scans. This weakly supervised approach processes MRI data as ordered sequences of 2.5D slabs, enabling patient-level PNI prediction without detailed slice- or voxel-level annotations. In validation studies, OAS-MIL demonstrated a mean AUROC of 0.770, surpassing existing volumetric and MIL baselines and indicating that axial order is a valuable inductive bias for this type of medical imaging analysis. AI

IMPACT This framework could improve preoperative risk assessment for certain cancers, potentially guiding treatment decisions.

    Order-Aware 2.5D Multiple Instance Learning for Preoperative MRI-Based Perineural Invasion Risk Assessment in Intrahepatic Cholangiocarcinoma

    arXiv:2609.11271v1 Announce Type: new Abstract: Perineural invasion (PNI) is an adverse histopathologic marker in intrahepatic cholangiocarcinoma (ICC), but it is usually confirmed only after resection. Preoperative T2-weighted MRI may provide noninvasive imaging cues predictive …
