摘要
In this study an in vitro multinuclear magnetic resonance spectroscopy (MRS) characterization of water soluble metabolites and of the lipid fraction obtained from 19 human gliomas (12 glioblastomas, 3 anaplastic astrocytomas, 2 anaplastic oligodendrogliomas and 2 oligodendrogliomas) with a total of 27 surgical specimens, is reported. Moreover, some in vivo H-1 MRS results are shown. The regional metabolic heterogeneity of glioblastomas, according to their morphological heterogeneity, is documented. For glioblastomas a specific in vitro H-1 MRS metabolite profile cannot be defined. Low and high grade oligodendrogliomas showed characteristic choline/creatine and alanine/creatine metabolite ratios. The spectroscopical characterization of histopathological factors concerning malignant gliomas is shown.
