Coloured diffusion tensor imaging (DTI) magnetic resonance imaging (MRI) scan of nerve pathways (orange) in the brain of a 44 year old male patient with a large lesion (purple) in the left temporoparietal region. The lesion is probably a glioblastoma, a malignant (cancerous) tumour that arises from the supporting glial cells in the brain. Diffusion tensor imaging measures the direction of water diffusion, which in the brain reveals the orientation of nerve fibres. This scan shows that some of the fibres have been displaced by the lesion. | |
