Recent experimental MREIT studies demonstrated conductivity image reconstructions of in vivo animal and human subjects with a few millimeter pixel size. Such a resolution could be sufficient to distinguish different human tissues for certain applications. In order to visualize a conductivity distribution within a tissue or a small animal, it is necessary to develop a high-resolution MREIT technique. The experimental results using a 4.7 T research MRI scanner with a multi-echo ICNE pulse sequence and high-performance RF coils demonstrate that we can distinguish two different anomalies in reconstructed conductivity images with a pixel size as small as 400 m.
