Liver tissues mainly consist of single cell, the variations of ion concentration and mobility inside the liver have similar pattern. This indicates that liver tissues can exhibit uniform distribution of electromagnetic tissue properties such as electrical conductivity. MREIT is typical method which can provide electrical conductivity information of suspicious tissue using a current-injection MRI method. Mapping of liver tissue damage using MREIT conductivity imaging may provide direct, immediate, and high sensitive information based on the changes of ion concentration and mobility at cellular levels. This study experimentally imaged in vivo liver tissue damage based on the changes of tissue conductivity.
