The contrast in electrical properties (EP’s) between regions of interest (ROI’s) is typically limited to less than 30%; within-subject and between-subject variability is also on the order of 30%. The SNR of reconstructed EP’s depends on the reconstruction method used; for Laplacian-based EP reconstruction, SNR depends on field strength, absolute value of EP’s and (ROI_size)3.5. At 3T and 7T, some applications for which relatively large ROI EP’s are sought have promising results using standard EP reconstruction. In order for EP mapping to become a reality at spatial resolutions useful for clinical diagnosis, more advanced reconstruction methodologies are likely needed.
