摘要:

近年来,基于扩散磁共振成像的大脑浅表白质纤维束成像技术取得了显著进展.浅表白质纤维束是连接皮层和皮层下神经结构的重要通路,在构建完整人类连接组和神经病理学研究中具有重要意义.本文首先总结了浅表白质纤维束成像技术的发展,其次着重讨论了不同方法在浅表白质纤维束分割中的优缺点,之后探讨了浅表白质纤维束图谱的构建流程,最后总结并对浅表白质纤维束成像技术与分割方法的研究方向进行了展望.

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.

Key words: diffusion magnetic resonance imaging, superficial white matter, tractography, segmentation, atlas
