MRI - magnetic resonance imaging is a complex process to measure brain structure, function and metabolism non-invasively. Because we are almost three quarters water, an MRI uses a strong magnetic field to align protons within the hydrogen atoms in this water and a radio pulse to temporarily 'turn' the protons. The different concentrations of water and the behaviour of different tissues and molecules in the scanner result in contrast between structures and advanced techniques reveal how the brain functions.
