Systematic Brain Tumor Conductivity Study with Optimized EPT Sequence and Reconstruction Algorithm

Introduction: With electric properties tomography (EPT) [1] we are able to measure the electric conductivity of tissue as an additional parameter [2,3], which might improve the diagnostic of brain tumors and other diseases using standard MRI-sequences. Different conductivity for grey matter and white matter was already shown [1]. Differences between tumors and healthy brain tissue were shown up to now for 4 cases [2,3]. In this study we systematically examined 12 patients with intracerebral tumors in reference to the electrical conductivity of the tissue using a conventional MRI-sequence that has not been used for brain EPT so far.
