In this work, we explored an alternative approach of using nominal $$$R_2^{\:'}$$$ instead of measured $$$R_2^{\:'}$$$ in separating the two susceptibility sources. The linear relationship between $$$R_2^{*}$$$ and $$$R_2^{\:'}$$$ was investigated and used to obtain the nominal $$$R_2^{\:'}$$$ values. The positive and negative magnetic susceptibility source maps using nominal $$$R_2^{\:'}$$$ showed similar susceptibility distribution to the map using measured $$$R_2^{\:'}$$$.
