(a) TE 31 msec. (b) TE 144 msec. MRS was performed to differentiate between high-grade glioma and tuberculoma. The lesion was diagnosed as a high-grade glioma. NAA is depressed. Lipid is elevated. Choline is markedly elevated. Cho : Cr is 3.28, and Cho : NAA is 3.17. Note that in this case diagnosed as high0grade glioma, myo-inositol at TE31 is not decreased.
