Myelin and iron are important substances for normal functions of the brain. The changes in their local concentrations have been reported in multiple brain disorders (e.g. demyelination in multiple sclerosis and iron deposition in deep gray matter in Parkinson’s disease). Hence, imaging their concentrations quantitatively using MRI has been an important topic of research. In this presentation, I will introduce myelin water imaging and magnetic susceptibility mapping as potential methods to quantitatively visualize myelin and iron in the brain.
