MM-NeuroOnco: A Multimodal Benchmark and Instruction Dataset for MRI-Based Brain Tumor Diagnosis

Researchers introduce MM-NeuroOnco, a large-scale multimodal dataset containing 24,726 MRI slices and 200,000 instructions for training AI models in brain tumor diagnosis. The benchmark reveals significant challenges in medical AI, with even advanced models like Gemini 3 Flash achieving only 41.88% accuracy on diagnostic questions.

General vs Domain-Specific CNNs: Understanding Pretraining Effects on Brain MRI Tumor Classification

Research comparing CNN architectures for brain tumor classification found that general-purpose models like ConvNeXt-Tiny (93% accuracy) outperformed domain-specific medical pre-trained models like RadImageNet DenseNet121 (68% accuracy). The study suggests that contemporary general-purpose CNNs with diverse pre-training may be more effective for medical imaging tasks in data-scarce scenarios.
