Mutual Distillation of Dual Foundation Models Achieves State-of-the-Art PET/CT Segmentation with Only 5 Labeled Cases

Researchers propose MuDuo, a mutual distillation framework that leverages two foundation models (SAM-Med3D for CT, SegAnyPET for PET) to distill knowledge into a lightweight student network for semi-supervised PET/CT segmentation. Achieving state-of-the-art performance on the AutoPET dataset with only 5 labeled cases, the approach eliminates manual prompts and maximizes unlabeled data utility.
