Native-space AI models outperform template-based for subcortical brain segmentation

Researchers have developed two U-Net-based pipelines for segmenting subcortical brain regions, specifically the Subthalamic Nucleus (STN), Red Nucleus (RN), and Substantia Nigra (SN), which are critical for neurosurgical planning in conditions like Parkinson's disease. The study found that pipelines operating in native-space consistently outperformed those using template-space coregistration, achieving higher Dice scores and lower Hausdorff distances for the STN. However, performance significantly dropped when models trained on high-field 7T MRI data were applied to lower-field 3T clinical images, with synthetic data offering only modest improvements in bridging this domain gap.

IMPACT Native-space segmentation offers improved patient-specific anatomical fidelity for neurosurgical applications, though domain adaptation for different MRI field strengths remains a challenge.

    Native space based pipelines outperform template space based pipeline in subcortical segmentation

    Accurate segmentation of subcortical regions is critical for neurosurgical planning and functional research. Most automated methods rely on template space coregistration, which may compromise patient-specific accuracy, particularly in small structures. We identify a need to evalu…
