Quantitative Susceptibility Mapping (QSM) enables accurate non-invasive monitoring of liver iron to guide iron-chelation therapy. Feasibility of a breath-hold sequence has been demonstrated in healthy subjects and in patients. In this work we investigate feasibility of a free-breathing navigator sequence in healthy volunteers to generate QSM maps and compare its correlation with the breath-hold sequence.
