Magnetic resonance-electrical impedance tomography (MREIT) is an imaging modality that reconstructs conductivity from magnetic field measurements generated by a current distribution. Since the conductivity values of malignant, benign, and normal tissues are significantly different, this information can be used in classification to improve specificity in breast cancer. There are several studies to determine the capabilities of MREIT using simple cases but none investigates performance in detecting irregular and more complex conductivity distributions, which models the real life cases more accurately. In this study, we showed that it is possible to resolve a 6mm inhomogeneity within an irregular region using MREIT.
