Biophysical mechanisms of MRI signal frequency contrast in multiple sclerosis
Phase images obtained with gradient echo MRI provide image contrast distinct from T1- and T2-weighted images. It is commonly assumed that the local contribution to MRI signal phase directly relates to local bulk tissue magnetic susceptibility. Here, we use Maxwell’s equations and Monte Carlo simulat...
