A Novel Dual-Stream Framework for dMRI Tractography Streamline Classification with Joint dMRI and fMRI Data

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • A novel dual-stream framework has been introduced for streamline classification in diffusion MRI (dMRI) tractography, which enhances the identification of functionally distinct white matter tracts by integrating both dMRI and functional MRI (fMRI) data. This method aims to improve the parcellation of the corticospinal tract (CST) into its four somatotopic subdivisions, addressing limitations in current classification methods that primarily rely on geometric features.
  • This development is significant as it represents a step forward in neuroimaging techniques, potentially leading to more accurate mapping of brain functions and better understanding of neurological conditions. By utilizing a pretrained backbone model alongside an auxiliary network for fMRI signals, the framework enhances the functional coherence of tract parcellation, which could improve clinical outcomes in neurology and rehabilitation.
  • The introduction of this dual-stream framework reflects a broader trend in medical imaging towards the integration of multiple data modalities to enhance diagnostic accuracy. Similar advancements in automated segmentation for body composition analysis and brain tumor classification highlight the growing importance of AI and deep learning in healthcare, emphasizing the need for innovative approaches to complex medical challenges.
