A Study on RF-Induced Heating of Passive Implantable Medical Devices at 5T MRI

This paper investigates the RF-induced heating of passive implantable medical devices (PIMDs) within the newly developed 5T whole-body MR system. Numerical and experimental studies identified the worst-case device length inside the ASTM phantom, which was then positioned at a clinically relevant location within an anatomically accurate human body model to evaluate RF-induced heating. The results indicate that the worst-case construct for RF-induced heating can be determined, and MR conditionality can be achieved for medical implants at 5T MRI.
