T2* relaxometry measurements of Liver Iron Concentration are demonstrated to be reliable and reproducible in publications. However, no suitable phantom exists for individual hospitals to validate the accuracy, reliability or precision of their methods. We demonstrate a novel phantom mimicking physiological T2* liver values for this purpose. The accuracy of 2 clinical sequences, reproducibility between 2 scanners and reliability of the phantom was investigated.
