MRI has shown to be able to quantify both magnetic and electrical property. Current studies normally perform one of the above methods individually. Being able to simultaneously quantify both susceptibility (χ) and conductivity (σ) mapping can be useful since misregistration can be alleviated due to separate measurements. Here, we introduce a simultaneous susceptibility and conductivity quantification method. Using a multiecho GRE sequence, the phase of the spins at TE=0 can be retrieved providing conductivity information while the subsequent phase evolution can be used for susceptibility mapping.
