Definition : [LI-RADS] Paucity of iron in solid mass relative to iron-overloaded liver: MRI: •
The observation is a solid mass AND The liver has any of the following: • Lower signal
intensity on second echo (longer TE) compared to first echo (shorter TE) on dual-echo
gradientecho sequence • Abnormally low signal intensity on T2W images • Abnormally
high R2* value on R2* maps (if obtained) AND • The observation has none of the above
features or has the features to a lesser degree than liver;
