3D diffusion tensor imaging MRI scan of a brain showing the presence of a large glioblastoma brain tumour (red) and nerve tracts (coloured lines). Glioblastoma is the most common primary brain tumour. Symptoms depend on the region of the brain affected, and include seizures, headaches and weakness on one side of the body. The most common symptoms are memory and personality changes due to its physical growth. Diffusion tensor imaging is a magnetic resonance technique that uses radio waves and a magnet to measure water diffusion in tissues. In the brain it can be used to build up detailed maps of the tracks of nerves, a process called tractography. | |
