To evaluate the feasibility of quantitative susceptibility mapping (QSM) in living mice liver and the robustness of QSM and transverse relaxation rate (R2*) based liver iron quantification. We show that QSM can be accurately performed in mice liver despite respiratory motion and that magnetic susceptibility measurements correlate more strongly with inductively coupled plasma mass spectrometry (ICP-MS) based iron quantification and have smaller standard deviations and narrower Bland-Altman agreement limits than R2* measurements.
