Espectroscopia multivoxel com tempo de eco curto: a razão colina/N-acetil-aspartato e a graduação dos astrocitomas cerebrais Multivoxel spectroscopy with short echo time: choline/N-acetyl-aspartate ratio and the grading of cerebral astrocytomas

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 (p<0,05) das rel...
