Axial T2 images with 1H-MRS voxels of two representative patients. After classification, a decision value is outputted from the predictive model. (A) A 44-year-old woman with a WHO grade II right frontal-insular astrocytoma is accurately classified into low-grade glioma with a high decision value (1.1). (B) A 41-year-old woman with a right frontal glioblastoma is accurately classified into high-grade glioma with a low decision value (0.3). The metabolite spectra were obtained from the blue box in the tumor region.(For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
