MedFlowBench (Radiology) - Longitudinal MRI Task: leaderboard

Metric: Accuracy (0-1, shown times 100) of the RANO response category on LUMIERE longitudinal brain MRI (139 questions: RANO response category from baseline and follow-up studies); 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: Around 2031. 14 models tracked.
