Accurate R2* value quantification is required for many applications. Multi-echo GRE imaging method is generally used to evaluate R2* value. However, the main drawback of this method is the influence of macroscopic B0 inhomogeneity which occurs as unintended phase dispersion. In this study, we have presented a volumetric R2* map including which corrects for macroscopic B0 inhomogeneity. The methods use a multi-echo 3D GRE approach with increasing field inhomogeneity compensation gradient and does not require additional scan time.
