Brain tumour, functional magnetic resonance imaging (fMRI) scan, from above. This is a 49 year old man with a brain lesion in the fronto-temporal cortex (top left), showing a grade 1 pilocytic astrocytoma (early stage, malignant brain tumour). This is a rare case, as pilocytic astrocytomas usually occur in young patients. The tumour has shifted the mid-line of the brain to the right. FMRI is used to detect changes in blood flow and blood oxygenation in the brain, highlighting areas of increased stimulation.
