Abstract :
Knowledge of the spatial distribution of electrical properties, namely dielectric constant, εr, and conductivity, σ, is valuable to various diagnostic and therapeutic technologies and for in vivo specific absorption rate (SAR) mapping in high-field magnetic resonance imaging (MRI). Electrical property mapping (EPM) is crucial to the early detection of various cancers for the reason that electrical properties (EP´s) of cancerous tissues at different stages are distinguishable from healthy ones. Moreover, EP´s show high tissue contrast therefore EPM are good to show anatomical structures of human body. This talk introduces the up to date research on non-invasive magnetic resonance imaging (MRI)-based electrical property mapping for human tissues, from both the literature and the speaker´s research group.
