The present invention relates to a method for performing electrical impedance tomography (EIT) by an MR system, wherein during the MR measurement continuous RF signals for an EIT measurement are emitted by at least one RF coil of the MR system, and continuous RF signals modulated by the object undergoing examination are received by the receiving coils of the MR system. An image of the object undergoing examination is determined, based on the modulated continuous RF signals, by an EIT technique.
