New MRI-based tissue electrical properties (EPs) mapping techniques had achieved higher accuracy and resolution increasing its chances to be used in several clinical applications. In this work, we describe a validation study for a technique called water-content-assisted electrical properties tomography (wEPT) based on in situ measurements of a brain-tissue-like phantom created by electrolytic protein solutions. The influence of inhomogeneous radiofrequency field distributions and its impact in wEPT reconstructions is also analyzed. Significant consistency between in vivo brain tissue estimations and phantom measurements was found, supporting the formalism and validity of wEPT for EPT studies.
