Correlation analysis between different characteristics of GST-P positive foci and liver iron content as well as % enhancement of MRI signal.

Parameters	Area of GST-P positive foci (mm2 cm−2)	Size of GST-P positive foci (mm2)	Number of GST-P positive foci
Iron content	Strong positive correlation (R2 = 0.85)	Strong positive correlation (R2 = 0.91)	Weak positive correlation (R2 = 0.36)
% enhancement (axial)	Strong positive correlation (R2 = 0.79)	Strong positive correlation (R2 = 0.95)	Weak positive correlation (R2 = 0.25)
% enhancement (coronal)	Weak positive correlation (R2 = 0.54)	Strong positive correlation (R2 = 0.99)	No correlation (R2 = −0.08)
