This study explores the opportunity of using ultra-high field (21.1 T) for producing electrical conductivity maps. Phantoms with known NaCl concentrations were used to compare conductivity maps generated by phase-based MREPT with actual values measured at 900 MHz with a dielectric probe. Phase-based MREPT also was evaluated for in vivo ischemic brain using an MCAO rat model. Increased conductivity values were noted in the stroked region of the rat brain.
