JANUS architecture improves CT triage accuracy and reliability

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 1 source

Researchers have developed JANUS, a new dual-stream architecture for automated CT triage that integrates anatomical information with visual data. This approach aims to improve accuracy across various pathologies and enhance reliability when faced with shifts in data distribution between institutions. In tests on the MERLIN dataset, JANUS achieved a macro-AUROC of 0.88 and demonstrated strong generalization to an external dataset, particularly for findings defined by size and attenuation. AI

    JANUS: Anatomy-Conditioned Gating for Robust CT Triage Under Distribution Shift

    Automated CT triage requires models that are simultaneously accurate across diverse pathologies and reliable under institutional shift. While Vision Transformers provide strong visual representations, many clinically significant findings are defined by quantitative imaging biomar…
