Fig 4.
Scatter plot of individual metabolite levels (millimoles per liter of VOI) for NAA (A), Cr (B), Cho (C), Glu (D), mIns (E), and percentage of sodium signal intensity (F) in grade II glioma and on the contralateral side are shown along with horizontal lines indicating the metabolite averages. Data from a reference region of homogeneous white matter are also included from a previous study.19 The sodium signal intensity in arbitrary units is reported for grade 2 glioma and from the contralateral side. Asterisks indicate significant differences between grade 2 glioma and control (NAA, Glu, mIns, and sodium).
