Electrical tissue conductivity is primarily determined
by concentration and mobility of ions in intra- and
extra-cellular fluids. The conductivity of biological
tissues show frequency-dependent behavior and its values
at different frequencies may provide useful diagnostic
information. MR-based tissue property mapping are widely
used imaging techniques which provided unique
conductivity contrast at different frequency ranges.
Recently, new method for data acquisition and
reconstruction for low- and high-frequency conductivity
images from a single MR scan was proposed. In this
study, we applied the simultaneous dual-frequency range
conductivity mapping to enhance its clinical potentials
through in vivo disease model animal imaging.
