摘 要：目的 研究腦損傷前后腦網(wǎng)絡(luò)的相應(yīng)改變。方法 通過多時(shí)點(diǎn)結(jié)構(gòu)磁共振體素分析技術(shù)，對(duì)急性腦梗死患者運(yùn)動(dòng)相關(guān)灰質(zhì)體積和白質(zhì)連系改變進(jìn)行研究。結(jié)果 急性皮質(zhì)下腦梗死后遠(yuǎn)隔部位灰質(zhì)和白質(zhì)繼發(fā)體積變化。結(jié)論 急性局灶性皮質(zhì)下梗死后，遠(yuǎn)隔部位運(yùn)動(dòng)相關(guān)腦網(wǎng)絡(luò)變化可對(duì)患者運(yùn)動(dòng)功能恢復(fù)起抑制或促進(jìn)作用。

關(guān)鍵詞：腦梗死 神經(jīng)功能恢復(fù) 磁共振

Abstract：Aim：To research the corresponding change of brain injury and brain networks. Methods： Through structure magnetic resonance imaging voxel analysis technique at multipoint， the patients with acute cerebral infarction associated with motion-ralated gray matter volume and white matter connection alterations were studied. Results： Distal parts of the gray volume and white matter connection in acute cerebral infarction patients were changed. Conclusion： After acute focal cerebral infarction，changes of distal brain network associatied with movement may inhibit or promot the recovery of motor function in patients.

Key Words：Cerebral infarction；Functional recovery；Magnetic resonance imaging
