Agreement on R2* iron level and fat fraction, between conventional MRI and IDEAL, as well as between readers

	ICC	Lower 95%CI	Upper 95%CI
Between conventional MRI and IDEAL
R2* Iron level, Reader1	0.253	−0.025	0.494
R2* Iron level, Reader2	0.291	0.016	0.524
Fat fraction, Reader1	0.026	−0.252	0.300
Fat fraction, Reader2	0.028	−0.249	0.302
Between readers
IDEAL R2* iron	0.971	0.950	0.984
IDEAL fat fraction	0.957	0.925	0.975
Conventional fat fraction	0.626	0.422	0.770

Agreement on R2* iron level and fat fraction between conventional MRI and IDEAL was poor. Using IDEAL, the agreement was high between readers on both R2* iron level and fat fraction. On conventional MRI, the reader agreement was moderate on fat fraction
