Measurement of Liver Iron Concentration by MRI Is Reproducible

Figure 4

Variability of estimates by MRI of liver iron concentration (LIC) in 9 patients and in the phantom. I–IX: real patients with different values ​​of LIC. MIO: moderate iron overload in the phantom. HIO: high iron overload in the phantom. Black rounds: measurements on the reference machine. “”: measurements on machine A. “+”: measurements on machine B. “−”: measurements on machine C. “∘”: measurements on machine “D”. High reproducibility can be observed, intra- and intermachines, for every patient. Phantom behavior is very similar to the patients.
