Published in Cancer Weekly, April 11th, 2000
P.E. Ricci and colleagues from the Barrow Neurological Institute reported positioning voxels at the enhancing edge of a tumor produced more accurate spectra concerning lesion histopathology than voxels positioned in the lesion center.
Researchers reviewed 50 single-voxel MR spectra from 43 patients with intra-axial brain tumors. The spectra were acquired using a fully automated stimulated-echo spectroscopy sequence.
Spectra were analyzed for the presence of choline, creatine, N-acetylaspartate (NAA), and...
