SpineMamba, a novel architecture for 3D spinal segmentation, integrates residual Visual Mamba layers and a learnable Vertebrae Shape Priors module to enhance anatomical understanding and capture long-range dependencies efficiently. The model achieved 94.40% Dice on CT and 86.95% Dice on MR datasets, showing improved accuracy and robustness across clinical imaging modalities.

Key insights

• Visual Mamba (VSS) blocks effectively process high-dimensional 3D medical data by efficiently capturing long-range spatial dependencies while maintaining linear computational complexity.
• Integrating a learnable Vertebrae Shape Priors (VSP) module dynamically provides crucial anatomical constraints, improving the model's ability to differentiate complex spinal structures and correct semantic errors.
• The synergy between efficient sequence modeling (Mamba) and explicit anatomical knowledge (VSP) is key to achieving robust and accurate segmentation across diverse imaging characteristics.
