| 摘 要： | 运用静息态功能磁共振成像技术(resting-state fMRI)研究慢性疼痛患者脑默认网络结构.通过选择双侧膝骨性关节炎(knee osteoarthritis,KOA)患者20例和正常志愿者20名,以后扣带回(posterior cingulated cortex,PCC)为种子点,分别进行fMRI扫描,分析配对两组受试者的脑功能连接情况.结果显示相对正常受试者,KOA患者存在异常脑功能连接,主要表现为PCC呈负激活,边缘叶、脑岛呈正激活. |

| Abstract: | The resting-state functional magnetic resonance imaging(resting-state fMRI) was used to study the brain default network structure of chronic pain patients.In this study,20 patients who afflicted bilateral knee osteoarthritis(KOA) and 20 normal volunteers were selected.Based on seed region of posterior cingu-lated cortex(PCC) of default-mode network,fMRI scan was performed to analyze connection of brain function of the two groups.The results suggest that patients with KOA show abnormal brain functional conne... |
