MR ISMRM Salt Lake City

MR safety of electrically conducive passive implants is directly related to heating of the tissue in close proximity to the device when subjected to RF powered E-fields. Cell death has been found to be a complex function of time and temperature. Current MR safety methodology relies primarily on experimental methods (ASTM F2182), that use a gel phantom which by its high viscosity negates connective heat transfer often providing overly conservative temperature results.
