Brain scan. Magnetic Resonance Image (MRI) showing a horizontal section of a normal brain. The two hemispheres of the brain are clearly visible separated by the longitudinal fissure (narrow and black at top centre). The two red areas at bottom left and right represent the cerebellum. It is a rounded structure located at the base of the posterior part of the brain,which is concerned with the maintenance of posture and balance and with the coordination of movement. MRI imaging does not use harmful ionising radiation: it analyses the behaviour of the nuclei of hydrogen atoms in the body subjected to a very strong magnetic field and detects these with radio waves | |
