MR-based Electric Properties Tomography (EPT) provides a noninvasive means to assess electric tissue properties, provides a framework for an accurate determination of local SAR, and a diagnostic parameter in oncology. We have employed a fast balanced SSFP sequence, which allows for abdominal imaging in a single breathhold. Phantom experiments and first in vivo conductivity scans in the liver of healthy adults are shown.
