| 摘 要： | 目的：分析急性脑梗死的氢质子磁共振波谱成像（^1Hnuclear magnetic resonance spectroscopy，^1HMRS）的成像特征，评价-HMRS对急性脑梗死的诊断价值。方法：17例急性脑梗死患者均行常规MRI（T1FLAIR（fluid affenuated inversion recovery，FLAIR）、T2WI、T2FLAIR）扫描及弥散加权成像（diffusion weighted imaging，DWI）和。HMRS扫描。多体素点分辨波谱（point resolved spectroscopy sequence，PRESS），TE144ms定域序列采集灶中心，比较分析代谢物出现概率。1～2个月后行常规MRI检查。结果：17例患者在1．05ppm处均出现倒置乳酸（Lac）峰，15例梗死区NAA峰不同程度降低，半暗带NAA峰正常。结论：磁共振。HMRS波谱分析与DWI相结合，可实现对急性脑梗死较为全面的评估。

| Abstract: | Objective: To retrospectively analyze the 1HMRS features of acute cerebral infraction,and to evaluate its value in the diagnosis.Methods: Seventeen patients with acute cerebral infraction underwent routine MRI(including T1FLAIR FSE-T2WI FLAIR and DWI) and 1HMRS.Multiple-voxel PRESS(144ms) sequence was performed and metabolite were analyzed.Follow-up routine MR was performed 1 to 2 months after the first MRI examination.Results: All 17 cases showed inversion lac in the 1.05ppm,15 did NAA decreased in different degree,9 did high Glx,13 did normal NAA in the half-hidden area.Conclusion: By combination of 1HMRS and DWI,full-scale evaluation of acute cerebral infraction can be achieved |
