Synopsis

Keywords: Safety, SafetyAlthough recent developments in flexible coils have allowed for imaging of the knee in a flexed or straight position, simulations for safety assessment are typically performed with both legs straight. Here we show first results of SAR simulations with both legs straight versus knee flexed with fields normalized as if imaging the knee that is changing position. Results indicate a decrease in maximum 10g SAR when the knee being imaged is flexed.
