In QSM, every effort is made to reduce background field induced by the air-tissue interfaces. In this abstract, we propose a method to: correct the phase of boundary regions by using background field extrapolation methods such as Taylor expansion; preserve the internal phase for the superior sagittal sinus (SSS) and transverse sinuses using an arterial-venous (MRAV) image; and predict the phase outside the brain and SSS using forward modeling. Further, we combine these steps to obtain an estimate of the venous oxygen saturation levels inside dural sinuses.
