     [摘要] 目的：探讨颅脑肿瘤1HMRS的改变在颅脑肿瘤的诊断及鉴别诊断应用中的意义。方法：观察36例颅脑肿瘤的1HMRS变化，对NAA、Cho、Cr峰的积分面积进行比较。结果：几乎所有颅脑肿瘤的NAA峰均下降，Cho/Cr下降；良恶性肿瘤之间、脑内外肿瘤之间的NAA峰值的比较差异有显著性，但其Cho、Cr峰值的比较及各代谢产物的峰值比值的比较差异无显著性。结论：1HMRS可无创性地活体分析及体现颅脑肿瘤的代谢状况，对其诊断及鉴别诊断有较大的价值。

    Abstract:Objective The effect of spectroscopy was discussed in diagnosing and distinguishing brain tumor.Methods The change of 36 brain tumor' spectroscopy was analyses.The itellge of 1HMRS was compared.Results The value of NAA and Cho/Cr was decreased obviously.The NAA value,between benign and malignant tumor and between intracerebral and extracerebral tumor,had significant effectiveness.But the Cho and Cr value and the peak ratio of metabolites had no significant effectiveness between benign and malignant tumor and between intracerebral and extracerebral tumor.Conclusion As a new research method,1HMRS had its special effectiveness. ......
