Abstract
A method of magnet resonance (MR) imaging of an object includes MR signal acquisition in a single scan providing information for electric properties imaging (EPT), which may include a phase map as well as tissue boundaries. The method includes: subjecting the object to a multi echo steady state imaging sequence or a fast spectroscopic imaging sequence that includes RF pulses and switched magnetic field gradients, wherein two or more echo signals are generated after each RF excitation; acquiring the echo signals; deriving a magnitude image and a phase map from the acquired echo signals, which phase map represents the spatial RF field distribution induced by the RF pulses in the object; and reconstructing an electric conductivity map from the magnitude image and from the phase map, wherein tissue boundaries are derived from at least the magnitude image.
