The motivation for the present work is the observed loss of signal and contrast when Thiel-embalmed human cadavers are imaged using clinical MR sequences. Here, we present the results from B1+ magnitude mapping of embalmed cadavers. EM simulations of the B1+ distribution in a visible male model were performed using a range of tissue electrical conductivity values. Our results show that RF penetration issues begin to develop for values of electrical conductivity as low as 2.6 S/m. We conclude that diminished RF penetration due to the high conductivity of the embalming fluids is the primary mechanism that affects MR imaging.
