Black blood T2* mapping on 1.5T is currently the gold standard for iron load assessment in patients with iron overload and plays a crucial role in patient management. Inaccuracies in T2* quantification at 3T due to greater artifact levels and higher B0 and B1 inhomogeneities have resulted in a lack of multi-center and multi-vendor validation studies to standardize T2* for iron overload assessment on 3T. In-vivo and In-vitro studies on 1.5T have suggested that T1 and T2 could be potential alternatives to T2*. In this study, we have demonstrated linear relationships for T1 Vs T2*, T2 Vs T2* and T1 Vs T2 at 3T suggesting that T1 or T2 could be potential alternatives to T2*.
