Susceptibility phase imaging with comparison to R2* mapping of iron-rich deep grey matter

► We studied susceptibility and filtering effects in deep grey matter phase imaging. ► Simulations and in vivo images produced similar results for phase imaging. ► We compared in vivo phase and R2* measures across structures and with different ROIs. ► Cross sectional phase measures depend on structure geometry and filter strength. ► Phase-R2* correlation depends upon ROI placement and baseline phase measure location.
