This work introduces a reference frame for the evaluation of single-voxel spectroscopy scans of brain tumors. The goal of this work is to stratify the classification of spectra based on metabolic features to maximize their specificity. The method was developed using decision trees and tested with different sample classifications that included tumor vs. non-tumor voxels and IDH vs. non-IDH tumors.
