The ability to accurately and non-invasively quantify IONPs is desirable for many emerging applications, including for the evaluation of iron overload in the human body. 3D UTE Cones has demonstrated ability to detect high iron concentration with shorter echo times. In this study, we aimed to make clear whether the non-Cartesian sampling of Cones trajectory affects the accuracy of QSM. By comparing three different kinds of UTE sampling trajectory, as well as different stretch factors of Cones, the results show that no significant differences between these UTE QSM results were found.
