Figure 2.
(a) In vivo spectra, at the eight (TE1, TE2) pairs of PRESS, from subjects with astrocytoma (grade II) and oligoastrocytoma (grade III) are shown together with voxel positioning (size 23×23×23 mm3) and LCModel fitting results. Spectra are normalized with respect to water signals. (b) Monoexponential T2 fitting of LCModel estimates versus TE.
