Task 4: Text-Conditional CT Generation

Without voxel‑level labels during training, systems must localize five key pathologies—pericardial effusion, pleural effusion, consolidation, lung opacity, and lung nodule—producing 3‑D heat‑maps that are scored on Dice, IoU, Hausdorff‑95, and Sensitivity against expert masks for 2000 hidden test scans.
