MR-based Electric Properties Tomography (EPT) provides a non-invasive means to assess electric tissue properties based on B1 field maps. It was recently shown that B1 phase is reflected in the phase of ultrashort echo time (UTE) signal. In this contribution we investigated the possibility of using UTE phase for in vivo conductivity mapping of the brain.
