Hierarchical Text-Guided Brain Tumor Segmentation via Sub-Region-Aware Prompts
arXiv CS.CV

ArXi:2603.21083v1 Announce Type: new Brain tumor segmentation remains challenging because the three standard sub-regions, i.e., whole tumor (WT), tumor core (TC), and enhancing tumor (ET), often exhibit ambiguous visual boundaries. Integrating radiological description texts with imaging has shown promise. However, most multimodal approaches typically compress a report into a single global text embedding shared across all sub-regions, overlooking their distinct clinical characteristics.
