Simultaneous T2* and field maps are calculated using an autoregressive moving average (ARMA) model on a cardiac multi-gradient echo acquisition. By using the field map, areas of high susceptibility are identified and removed for T2* quantification in the left ventricle. This can aid in precise T2* mapping for improved cardiac iron concentration assessment.
