Numerical and experimental study of RF‐induced heating of passive implantable medical devices at 5T MRI
This study systematically evaluates RF-induced heating in orthopedic implants within the newly approved 5T whole-body MRI, demonstrating that implant length, positioning, and surrounding media significantly impact heating risks. The findings highlight the necessity for updated MRI safety guidelines at UHF strengths, as implant safety conditions at 5T systems may differ from those at 1.5 and 3T MRI systems.
