Abstract

Objective To evaluate the performance of multi-voxel magnetic resonance spectroscopy (MRS) in differentiating low grade gliomas. Methods Retrospective study was done on 30 cases of grade Ⅱ gliomas (16 cases of astrocytoma and 14 cases of oligodendroglioma) who received MRS. Concentrations of metabolites and relative ratios were compared between the subtype astrocytoma and oligodendroglioma. Stepwise Logistic regression was applied to find the related factors. Results The relative concentrations of Cho and Cr from astrocytoma were higher than those of oligodendroglioma. The relative ratios Cho/Cr and Cho/NAA were also higher than those of oligodendroglioma (P<0.05). Cho was the related factors in differentiating low grade astrocytoma and oligodendroglioma by Logistic regression model (OR=1.153,95%CI: 1.083-1.227,P<0.05). Conclusion The relative concentrations of Cho could be the important indexes to differentiate astrocytoma and oligodendroglioma in clinic.
