This study investigates the
possibility to extend the water-content based electrical properties tomography
(wEPT) technique to lower frequencies. The wEPT approach assumes that electrical properties (EP) of brain tissues can be estimated from water-content (WC) which
is derived from two T1-weighted MRIs. Adapted wEPT model parameters were
evaluated from ex-vivo measurements
of calf brain tissue samples. We performed wEPT estimations in an in-vivo
rat brain tumor model, followed by ex-vivo measurements of brain
extracted samples. Results predict good correlation between WC ex-vivo measurements and in-vivo wEPT estimations. Yet, mapping
EPs with wEPT at lower frequencies needs further investigation.
