Spectral array corresponded to (A) summed and (B) difference with the Lac-edited spectra. Voxels possessing Lac or Lip with signal-to-noise ratio five.0 are labeled, and voxels within the T2 lesion inside the PRESS volume (T2L) are outlined in black thick line.Fig. six.

Postcontrast T1-weighted FLAIR images and 3D (non-Lac-edited) MRSI from 2 sufferers (A, B) with GBM at F2mo. Voxels with Cho-to-NAA index (CNI) .3.0 are highlighted in dark grey, voxels in light grey had CNI between 2 and 3, and voxels in the T2 lesion inside the PRESS volume (T2L) were outlined in black thick line. Numbers within the spectral array represent values of normalized creatine (nCr). Patient A had a brief OS of 11 mo and patient B died at 61 mo.Table three.
