Correlation between the three quantitative magnetic resonance imaging (MRI) methods and two histological scoring systems for liver iron storage (Spearman’s rank correlation test).

Histological Scoring of LIC	SIR According to Rennes University	R2* Relaxometry (Classical)	R2* Relaxometry (IDEAL-IQ®)
Deugnier’s and Turlin’s histological scoring	r = 0.8329 p = 0.0002	r = −0.9099 p < 0.0001	r = −0.872 p = 0.0018
Scheuer’s classification	r = 0.7106 p = 0.0009	r = −0.7453 p = 0.0004	r = −0.7142 p = 0.0120
