Outcome Measures
Primary Outcomes (1)
Calibration curve of liver R2* vs LIC measured by Ferriscan at each of the sites
The hypothesis is that equivalence between R2 measured with different protocols with higher repeatability than standard MRI iron imaging measurement and with linear calibration to liver iron concentration will be demonstrated. This project will be considered a success if the reproducibility of confounder-corrected R2 MRI is established: the hypothesis is that calibrations at all sites will be equivalent.

Patient Group
Subjects with known or suspected iron overload will undergo serum ferritin measurement and an MRI scan.
Control Group
Subjects with no known history of iron overload or liver disease will undergo an MRI scan.
