(a) TE 31 msec. (b) TE 144 msec. MRS was performed to differentiate between high-grade and low-grade glioma. The lesion was diagnosed as a high-grade glioma. NAA is reduced. Lipid and lactate are elevated. Choline is markedly elevated. Cho : Cr is 4.74, and Cho : NAA is 5.19. However, at TE31, myo-inositol is slightly increased. Myo-inositol increase has been associated with low-grade gliomas (58).
