3-T MRI implant safety: heat induction with new dual-channel radiofrequency transmission technology

This study aimed to investigate whether different transmission settings of the dual-transmit technology may influence the amount of heat induction around an implant material dependent on its location within the magnetic field. The study results indicated that elliptically polarized transmission showed lower heating around implants compared to the circularly polarized transmission as commonly used in the single-transmission system and that less heating was observed for both transmission settings closer to the magnet isocentre.
