Abstract
Disclosed are an apparatus and method for imaging electrical properties of brain tissues including conductivity and permittivity using magnetic resonance imaging (MRI) signals. Electrical properties images for conductivity and permittivity of brain tissues may be obtained with high spatial resolution and high accuracy, without using a derivative which significantly amplifies noise in an MRI image, by calculating water content based on a ratio of MRI signals, calculating electrical properties from the calculated water content, and acquiring an electrical properties image for the calculated electrical properties.
