Figure 1: Left fronto-insular glioma, progressing from low grade to high grade, followed by DT metrics. MRI of the patient done at three time periods is illustrated in three separate rows. Each column displays axial sections in the following order: T2-weighted, contrast-enhanced T1-weighted, relative CBV, MR spectroscopy, and FA map. The gradual increase in extent of the lesion can be appreciated along with increasing mass effect. The initial focus of hyperperfusion is seen to increase significantly while there is increase in the Cho/Cr and decrease in NAA/Cr ratios. FA maps reveal an initial displacement of white matter tracts in the forceps minor with progressive decrease in anisotropy in this region, suggesting possible infiltration
