Region-adaptive multimodal learning with morphology-guided feature modulation for brain tumor segmentation

Segmentation of brain tumors using multimodal MRI is difficult because patients have different appearances and structure of tumors. The existing methods of multimodal feature fusion achieve global feature integration but they do not recognize the unique properties which exist in each tumor subregion. Subregion-specific...

A 3D residual U-Net with attention-driven spatial pyramid pooling for accurate multimodal MRI brain tumor segmentation

Experimental results demonstrate that the proposed 3D U-Net achieves superior performance, with a Dice coefficient of 0.83 and a Jaccard index of 0.82, outperforming baseline models across all evaluation metrics, indicating strong generalization capability.
