MRI safety for patients carrying metallic implants, whose prevalence grows continuously, has become a matter of concern, so that risk assessment for passive implanted medical devices is important for both radiologists and implant manufacturers. A wide analysis of parameters influencing the thermal effects of Gradient Coil fields is here performed. Results show that it seems possible to identify some general rules related to this cause of heating, also in view of future standardized approaches.
