Purpose: To evaluate magnetic resonance spectroscopy (MRS) in the assessment of brain tumors and grading brain glioma. Patients and methods: Retrospective study was done for 42 patients with diagrammatic representations suggested by the author for the assessment of MRS data. Results: Pathology grading was correlated with metabolic ratios in cases of brain glioma. Ratios higher than 1.5 for either Cho/Cr or Cho/NAA were consistent with tumors and ratios higher than 2 were consistent with high grade glioma or metastases. Conclusion: MRS can be used to grade cases of brain glioma. Diagrammatic representations and a diagnostic approach were suggested by the author to simplify clinical practice. © 2012 Egyptian Society of Radiology and Nuclear Medicine.
