Electrical tissue conductivity is primarily determined
by concentration and mobility of ions. If electrical
current is carried by dissolved ions, the more ions
generate more currents. In addition, the mobility of
ions is restricted by heterogeneous membrane, current
density of tissue dependent on the physical environment
even though it has uniform ion concentration. Using
MREIT technique, we provide electrical
conductivity-based metabolite mapping with highly
sensitive to its concentration changes. Together with in
vitro measurement of metabolites by concentration
changes, we performed phantom imaging to evaluate the
proposed method showing a significant relationship
between concentration and electrical conductivity of
brain metabolites.
