Improving Pre-trained Adult Glioma Segmentation Models Using only Post-processing Techniques
Researchers are developing advanced post-processing techniques to improve the accuracy of brain tumor segmentation models, particularly for gliomas. These methods aim to refine segmentations produced by large pre-trained models, addressing issues like false positives and slice discontinuities. One approach focuses on adaptive post-processing, showing significant improvements on BraTS 2025 challenge tasks. Another strategy involves a flexible pipeline that combines multiple models and uses radiomic features for tumor subtyping and lesion-wise ensemble optimization. A third method, AdaMM, tackles missing modalities in multi-modal MRI by employing knowledge distillation and adaptive refinement modules to enhance robustness and accuracy, especially in challenging clinical scenarios.
