Researchers have developed an open-source foundation model for segmenting tumors in FDG PET/CT scans, integrating anatomical and metabolic data from the outset. This model, trained on nearly 5,000 harmonized scans from multiple public datasets, demonstrates significant label efficiency, achieving comparable performance to full-dataset models with only 10% of the labeled data. The framework utilizes a hierarchical UNet backbone with early channel-wise concatenation and a masked autoencoding objective, offering a robust basis for advancing automated oncologic imaging and reducing annotation needs.
