Claim:
1. A magnetic resonance imaging (MRI) apparatus for conductivity and susceptibility image reconstruction, the MRI apparatus comprising: an image acquisition part configured to acquire a multi-echo gradient echo image; a susceptibility reconstruction part configured to reconstruct a susceptibility image from the multi-echo gradient echo image based on a phase change of the multi-echo gradient echo image determined according to an increase in time of the multi-echo gradient echo image; a zero echo phase estimation part configured to estimate a zero echo phase at zero echo time of the multi-echo gradient echo image based on a linearity of the phase change determined by the susceptibility reconstruction part; and a conductivity reconstruction part configured to reconstruct a conductivity image from the multi-echo gradient echo image according to the zero echo phase estimated by the zero echo estimation part.
