摘 要：目的 研究腦損傷前后腦網絡的相應改變。方法 通過多時點結構磁共振體素分析技術，對急性腦梗死患者運動相關灰質體積和白質連系改變進行研究。結果 急性皮質下腦梗死后遠隔部位灰質和白質繼發體積變化。結論 急性局灶性皮質下梗死后，遠隔部位運動相關腦網絡變化可對患者運動功能恢復起抑制或促進作用。

關鍵詞：腦梗死 神經功能恢復 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
