Quantitative Susceptibility Mapping (QSM) to Guide Iron Chelating Therapy

Investigators will validate hepatic QSM (hQSM) using histological examination and chemical measurement of liver iron concentration (LIC). Patients will undergo clinical MRI in Aim 1. In patients with increased LIC their liver explants will undergo MRI, pathological examination, and chemical determination of the LIC.

Investigators will be able to validate hQSM in measuring liver iron concentration (LIC) by comparing it to this traditional MRI technique
