Research Progress on Tractography of Superficial White Matter Based on Diffusion Magnetic Resonance Imaging

Abstract

In recent years, significant progress has been made in tractography of superficial white matter in the brain based on diffusion magnetic resonance imaging. Superficial white matter fiber tracts serve as critical pathways connecting cortical and subcortical structures, playing a vital role in the construction of complete human connectome and neuropathological studies. This paper first summarizes the development of superficial white matter tractography techniques. Subsequently, it evaluates the strengths and weaknesses of different methods employed in superficial white matter fiber tract segmentation. Afterwards, the construction process of superficial white matter fiber tract atlas is discussed. Finally, this review concludes with an outlook on future research direction of superficial white matter tractography technology and segmentation methods.
