Water-Content-Map Assisted Electrical Properties Reconstruction of Brain Tissue at 3T

Measuring the electrical properties of tissue non-invasively with high resolution and accuracy has practical significance for several diagnostic and therapeutic applications in the biomedical field. In this work, the relationship between the electrical properties of tissue and their amount of electrolyte content is exploited. This model is a combination of previous observations of mixture theory and experimental measurements given by literature. We validate our formulation by performing in-vivo EPT mapping of brain tissue at 3T MRI. Great accuracy with not precedent resolution was achieved and we believe this method can have a great impact in EPT estimations.
