Title

Analysis of Glioblastoma Multiforme Tumor Metabolites Using Multivoxel Magnetic Resonance Spectroscopy

Pages

  107-115

Abstract

 Background: Glioblastoma multiforme (GBM) is the most common and deadly type of primary brain tumor in adults. Magnetic resonance spectroscopy (MRS) is a noninvasive imaging technique used to study metabolic changes in the brain tumors. Some metabolites such as Phosphocholine, Creatine, NAA/Cr, and Pcho/Cr have been proven to show a diagnostic role in GBM. The present study was conducted to analyze important metabolites using MRS multiVoxel in GBM tumor. Methods: In this study, information was collected from 8 individuals diagnosed with GBM using Siemens multiVoxel MRS with a magnetic field strength of 3 T. Data were obtained by Point-Resolved Spectroscopy (PRESS) protocol with TE=135 ms and TR=1570 ms. NAA, Pcho, Cr, Ala, Gln, Gly, Glu, Lac, NAAG, and Tau metabolites were extracted and evaluated statistically. Results: Given total number of normal Voxels and total number of all Voxels, levels of Cr, Glu, NAA, NAAG, and Gly/Tau ratio in healthy Voxels were significantly higher than tumoral Voxels (p=0. 005, p=0. 03, p<0. 001, p<0. 001 and p=0. 041, respectively). In contrast, levels of Gly, Gln, Tau, Lac/Cr, Pcho/Cr, Pcho/NAA, Lac/NAA, and Gln/Glu ratios in tumoral Voxels were significantly more than healthy Voxels (p=0. 001, p= 0. 037, p<0. 001, p=0. 010, p<0. 001, p<0. 001, and p=0. 024, respectively). However, levels of Lac and Pcho had no significant difference in the two types of Voxels. Conclusion: In summary, compared to patients with glioblastoma with 1H-MRS, the Pcho/Cr and Pcho/NAA ratios, and NAAG are the most important parameters to differentiate between tumoral and normal Voxels.
