Popis:	Avaliou-se a relação colina/N-acetil-aspartato (Co/NAA), obtida pela espectroscopia multivoxel com tempo de eco (TE) curto, na graduação histológica dos astrocitomas encefálicos (graus I, II e III-IV), comparando com o parênquima cerebral normal. Observou-se aumento significativo (pThe choline/N-acetyl-aspartate (Cho/NAA) ratio, obtained by the multivoxel spectroscopy with short echo time (TE), was evaluated, in the histological grading of the brain astrocytomas (grades I, II and III-IV) in comparison with the normal cerebral parenchyma. A significant increase (p
