In ischemic stroke, [Na+] increases due to ischemia and subsequent disturbance of ion homeostasis. Recently, electrical properties tomography (EPT) was introduced as a new contrast in MRI. This contrast enables us to visualize the local electrical properties of tissue, being the conductivity and permittivity; the electrical conductivity is related to [Na+]. In this study, it was shown that electrical conductivity was locally elevated in the tissue affected by the infarction.
