Coloured axial magnetic resonance imaging (MRI) scan of the brain of a female 34-year-old patient with multiple sclerosis. The patient presented with gait disorders, asthenia (physical weakness) and slurred speech: presence of numerous diffuse hipersignals of the white matter orienting the diagnosis of multiple sclerosis. MS is due to the destruction of the protective myelin sheaths surrounding the axon nerve fibres of the brain and spinal cord. This is a T2 MRI scan, with the use of gadolinium as a contrast medium.
