In vivo proton MR spectroscopy: the diagnostic possibilities of lipid resonances in brain tumors.

摘要: The lipid resonances detected in proton MR spectra of brain tumors were evaluated from the diagnostic point view. Seventy five non-radiated examined vivo and lipids 29% anaplastic astrocytomas grade III, 60% glioblastomas multiforme 50% metastatic tumors. Lipids also all abscesses an epidermoid cyst. No benign (low pilocytic astrocytomas, oligodendrogliomas, meningiomas, pituitary adenomas etc.). Thus, presence is indicative malignancy (with a few exceptions).
