MREIT can provide conductivity information of suspicious tissue using a current-injection MRI technique. To support its clinical significance, we should demonstrate that the conductivity image provides meaningful diagnostic information that is not available from other imaging modalities. To investigate any change of electrical conductivity due to brain abscess, canine brains having a regional abscess model were scanned along with separate scans of canine brains having no disease model. Conductivity images shown in this study indicated that time-course variations of conductivity contrast between normal and abscess regions are distinguishable in a different way compared with conventional MR image techniques.
