| 摘 要： | 目的：探讨MRI对脑胶质瘤病的诊断价值。方法：分析7例脑胶质瘤病的MRI表现。结果：7例胶质瘤病均侵犯2个脑叶或以上，5例侵及大脑深部结构，病变均呈长T1、长T2信号，占位效应不明显，未见明显强化，DWI示部分病灶呈高信号，ADC图呈低信号，且ADC值低于正常脑实质值，MRS波谱示病变区NAA峰明显降低，2例CHO峰明显升高，未见明显LAC峰，病理证实为脑胶质瘤病。结论：MRI是目前诊断脑胶质瘤病的首选影像学诊断方法。

| Abstract: | Objective: To investigate the value of MRI in diagnosis of gliomatosis cerebri.Methods: Analyzed the MRI features of gliomatosis cerebri(GC). Results:Tumours involved at least two cerebral lobes in all patients,with extension to the deep part in 5,the tumour process presented hyperintensity or slight hyperintensity on T2 weighted images and slight hypointensity on T1 weighted images in all patients,no obvious enhancement occurred in most of patients.Part of the tumour was appeared hyperintensity on diffusion weighted images and hypointensity on ADC map.The peak of NAA were decrease conspicuously,two of them the peak of CHO were increase obviously and the peak of LAC were absent with MRS.All cases were identified with pathological examination.Conclusion: MRI is the best choice of the methods in diagnosis of gliomatosis cerebri. |
