Ultrashort echo time (UTE) imaging is a valuable technique for imaging short T2 and T2* samples. While the mDIXON-quant sequence enables reliable separation of water and fat signals, and measurement of fat fraction. With introduction of multiple echo acquisition, both the UTE and mDIXON-quant sequence can be used for measurement of the quantitative R2* values. This study investigated the correlation between R2* values measured by UTE and mDIXON-quant sequences. Results show that a moderate correlation between R2 values by the two methods, and R2* values measured by UTE were slightly higher than those by mDIXON-quant.
