: The same patient population was presented in two other papers were we investigated the regional differences in T1 mapping within the liver [] and compared the value of SWI and T2* mapping [] in diffuse liver disease. The current paper compares T1 relaxation rates of liver and the spleen with and without normalization to the blood pool. Even if MRI data are from the same patient population, objectives and presented results are completely different and there is no significant overlap with the scope and results of the current paper in any of those.1.
