Electric Properties Tomography was performed in 24 glioma patients, and the electrical conductivity characteristics of glioma were determined noninvasively. Diagnostic performance of electrical conductivity in distinguishing glioma grades was also evaluated. Validity of noninvasive electrical conductivity measurement was proved by correlating with the conductivity values measured ex vivo by a dielectric probe.
