Magnetic Resonance Spectroscopy

Basically it is quantifying various metabolites within a sample of tumour tissue.

  • N-acetylaspartate (NAA)
    • Decreased NAA ==> primary brain tumor
  • Choline
    • Cell membrane component
    • Choline/Creatine ratio
  • Lactate
    • Glycosis and necrosis
  • Creatine
    • Marker for energy metabolism
  • Hydrogen MRS
