The aim of our study was to assess the feasibility of quantitative susceptibility mapping (QSM) as a tool to quantify bone marrow iron level non-invasively. Nine rabbits were scanned before and after iron accumulations, and bone marrow susceptibility values of these rabbits were evaluated from the reconstructed QSM images. The results showed a linear correlation between the measured susceptibility changes and the injected iron doses.
