MRI is currently utilised as a non-invasive
method for liver iron concentration (LIC) estimation and has essentially
replaced liver biopsy. FerriScan derived LIC is considered the “gold standard”
but has associated increased costs and delay results from required external
data transmittal. There is no universal agreement or standardization of R2*
derived LIC methods. We describe an optimized R2* method with noise corrected post
processing of data for LIC estimation with simultaneous comparison to FerriScan
derived LIC. Our results show very good correlation between R2* LIC and FerriScan
LIC with potential for substitution of the latter with our R2* technique.
