Magnetic Resonance Electrical Property Tomography (MREPT) allowed the evaluation of the intra- and extracellular ionic changes in a rat model of brain tumor. A multi-echo T₂-weighted pulse sequence was used with 10 echos to map the B₁ field and reconstruct the tissue conductivity at 9.4T. Higher conductivity values were measured in the tumors compared to the healthy brain tissue, suggesting an increased ionic content and mobility in the tumor.
