摘要
目的 探讨磁共振成像 (MRI)结合氢质子磁共振波谱 (1H MRS)以提高脑胶质瘤的诊断正确性。方法 对 2 0像MRI显示不典型胶质瘤表现者配合1H MRS检查 (测NAA、Cho、Cr、及Lac波 )进行综合诊断。结果 1H MRS显示肿块区NAA下降、Cho升高、Cr略下降或变化不明显。结论 MRI影像结合1H MRS分析 ,既能提高脑胶质瘤的诊断正确性 ,对临床选择导航、立体定向活检、γ 刀等治疗方案 。
Objective To evaluate diagnostic accuracy of brain gliomas with MRI and proton MR spectroscopy.Methods ()~1H-MRS examination (NAA,Cho,Cr and Lac wave)were carried out for diagnoses in 20 cases with characteristic of atypical gliomas in MRI.Results Decreased NAA and increased Cho,more decreased or more changed Cr was showed in ()~1H-MRS.Conclusion It may be playing an important clinical role not only in evaluating diagnostic accuracy of brain gliomsa but in selecting clinic therapy plan of guidance operation,stereotactic biopsy and gammar-ray knife in combination with MRI and ()~1H-MRS analysis.
