Quantitative Susceptibility Mapping (QSM) is a technique to describe local susceptibility distribution in the human body . Especially, QSM has the potentials to provide oxygen metabolic information of the venous structure in the brain such as dural sinuses. Among the group of this sinuses, the superior sagittal sinus (SSS) often have been investigated in, neurovascular researches such as Parkinson's disease, headache and stroke . However, the SSS of the susceptibility mapping are often eroded in the conventional QSM pipeline. In this study, we investigate the reliability of QSM for the SSS from single echo 3D GRE phase using the simulated phase data.
