Abstract
Magnetic resonance electrical impedance tomography (MREIT) and magnetic resonance electrical property tomography (MREPT) are new medical imaging modalities capable of visualizing distributions of electrical properties inside an electrically conducting object such as the human body. MREIT provides conductivity images at frequencies below a few kHz by processing MR phase images subject to externally injected currents, while MREPT provides both conductivity and permittivity images at the Larmor frequency (128 MHz at 3 T) by processing B1 maps. In this paper, we present experimental results of both MREIT and MREPT and highlight their distinct features in probing and visualizing the same object.
