Researchers have developed a novel framework for learning representations from 18F-FDG PET imaging data, specifically designed for content-based retrieval of intra-tumour heterogeneity. This weakly supervised method leverages H&E stain information during training while enabling PET-only inference. The approach utilizes a teacher-student training strategy to generate voxel representations, leading to global and hotspot-conditioned embeddings, and maps of intra-tumour heterogeneity in oesophageal cancer cases. Evaluation demonstrated that incorporating pathology-informed supervision and hotspot modeling significantly improved retrieval performance compared to conventional PET representations. AI
IMPACT This research could lead to more accurate and efficient methods for analyzing medical images, potentially improving cancer diagnosis and treatment planning.
