YOLO-LS: a novel deep learning framework for brain tumor segmentation in Magnetic Resonance Imaging
This study introduces YOLO-LS (Lightweight Segmentation), an enhanced deep learning framework for brain tumor segmentation in Magnetic Resonance Imaging (MRI). Built upon the YOLO11n-seg architecture, YOLO-LS incorporates three key innovations: a ShuffleNet V1 backbone for lightweight feature extraction, DySample for dynamic upsampling to preserve fine-grained details, and a C3k2-PoolingFormer module for efficient cross-scale feature fusion and global context capture. Evaluated on internal (Figshare) and external (Kaggle) datasets, YOLO-LS achieves superior segmentation precision with significantly reduced computational costs (8.1 GFLOPs, a 15.6% reduction) and improved boundary adherence (HD95 of 4.35 ± 0.34 mm). The framework demonstrates strong generalization and interpretability, offering a promising solution for real-time brain tumor segmentation in resource-constrained clinical settings.

YOLO-LS outperforms existing methods in Dice coefficient and HD95, indicating superior segmentation accuracy and boundary delineation while maintaining the lowest computational cost.
Clinical Impact
Improved Boundary Delineation for Glioma
Grad-CAM heatmaps confirm YOLO-LS's precise focus on tumor cores and boundaries, crucial for identifying infiltrative boundaries in complex cases like gliomas. This translates to enhanced accuracy in surgical planning and radiotherapy, addressing a key challenge where traditional methods struggle with blurred boundaries and heterogeneity.
