MedFlowBench (Radiology) - Brain MRI Localization: leaderboard
Metric: Localization (0-1, shown times 100) on UCSF-PDGM multi-sequence brain MRI (495 cases: tumor diagnosis): share of cases whose reported RAS point lies inside the hidden tumor mask; the model drives 3D Slicer through the MedOpenClaw runtime with viewer-native actions only (series selection, scrolling, windowing, prealigned fusion), inspecting the complete study within a 20-round budget and returning an answer with structured evidence (Track A); higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 14 models tracked.
