Advanced MRI brain scan. This 3D magnetic resonance imaging (MRI) scan of a normal human head and brain has been produced by the 3T MRI scanner at Neurospin, one of the most advanced MRI research centres in the world. The front of the brain is at left. The coloured lines indicate some of the main neural pathways in the brain. Brain areas include the brainstem (pink), the cerebrum (red) and the cerebellum (yellow). Neurospin has 3T and 7T scanners. The 'T' designations refer to the magnetic field strengths of 3 Tesla and 7 Tesla. These are extremely strong magnetic fields, and so this technique is known as ultra high-field magnetic resonance imaging. The high magnetic field strength allows detailed examination of the brain and brain disorders. Neurospin was founded in 2006, and is located near Paris, France.
