Magnetic susceptibility is a physical quantity that defines how strongly a material can be magnetized by an applied magnetic field. We are developing MRI-based methods to measure the spatial distribution of magnetic susceptibility in biological tissues. This is possible because magnetic susceptibility changes the spatial pattern of magnetic field which in turn changes the frequency of MRI signal. These methods are now generally called quantitative susceptibility mapping (QSM) and susceptibility tensor imaging (STI).
