Brain cancer. Coloured magnetic resonance imaging (MRI) scan (upper right) and a neurospectrograph (blue line) showing a glioblastoma of the brain. This is a malignant cancer of the glial cells, which support the nerve cells in the brain. The graph shows peaks relating to the presence of the metabolites of certain brain chemicals. These are lactates and lipids (Lac/Lip), N-acetylaspartate (N-aa), glutamate (Glx), creatine (Cr), choline (Ch) and myo-inositol (MI). Here, the amount of Glx is above normal, indicating the presence of tumorous infiltrates in the brain around the tumour (highlighted by a square on the scan). Most glioblastomas are fatal.
