NOVA: A Benchmark for Anomaly Localization and Clinical Reasoning in Brain MRI
NOVA is a new evaluation-only benchmark of rare brain MRI pathologies where GPT-4o, Gemini 2.0 Flash, and Qwen2.5-VL-72B all exhibit large performance drops across anomaly localization, image captioning, and diagnostic reasoning.
