摘要
脚桥核虽然在帕金森病冻结步态(FOG)发生中起着重要的作用,但越来越多研究表明FOG的发生是认知和运动功能损害相互作用导致的,其中认知功能受损起主导作用。扩散张量成像(DTI)的基于体素分析(VBA)方法和基于纤维束骨架的空间统计方法 (TBSS)具有客观性、全面性和可重复性的特点,是研究神经系统疾病的常用方法,对于探究FOG的发病机制具有重要价值。就近年来DTI技术在PD病人FOG中的研究进展予以综述。
        Pedunculopontine nucleus plays an important role in the pathophysiological mechanism of freezing of gait(FOG) in patients with Parkinson's disease, but accumulative evidences have shown that the occurrence of FOG is the interaction of cognitive malfunction and motor malfunction, especially the impairment of cognitive function. Owing to their objectivity, comprehensiveness and repeatability, voxel-based analysis(VBA) and tract-based spatial statistics(TBSS) based on diffusion tensor imaging(DTI) are the useful methods for the study of pathophysiological mechanisms in central nervous system diseases. We reviewed the research progress of DTI techniques in FOG.
