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.
