OBJECTIVE: To investigate the characteristics of brain network centrality in patients with cervical spondylotic myelopathy (CSM) by using degree centrality (DC) based on resting-state functional magnetic resonance imaging. METHODS: We recruited 20 patients with CSM, along with 20 healthy controls (HC) who were matched in terms of age, gender, and educational background. The DC method was utilized to evaluate the changed spontaneous brain activities. The relationships between the DC values of different brain regions and the clinical features were analyzed by means of Pearson correlation analysis. RESULTS: Compared with HC, CSM group showed decreased DC values in the left medial frontal gyrus, middle temporal gyrus and angular gyrus, and increased DC values were found in the left middle occipital gyrus, right supplementary motor area ( < 0.05). There was no significant correlation between DC values of abnormal region and clinical function score of CSM patients ( > 0.05). CONCLUSION: CSM patients have abnormal DC distribution in the whole-brain functional networks, which might be related to cortical reorganization after chronic spinal cord injury.
目的:基于静息态功能磁共振成像,采用度中心性(DC)研究脊髓型颈椎病(CSM)患者脑网络中心性的特征。 方法:招募20例CSM患者以及20名年龄、性别和教育背景相匹配的健康对照(HC)。采用DC方法评估自发脑活动的变化。通过Pearson相关分析分析不同脑区DC值与临床特征之间的关系。 结果:与HC相比,CSM组左侧额内侧回、颞中回和角回的DC值降低,左侧枕中回、右侧辅助运动区的DC值升高(<0.05)。异常区域的DC值与CSM患者的临床功能评分之间无显著相关性(>0.05)。 结论:CSM患者全脑功能网络中DC分布异常,这可能与慢性脊髓损伤后的皮质重组有关。
