Abstract
Magnetic Particle Imaging (MPI) is a 3D imaging technology that offers high temporal resolution without ionizing radiation, making it ideal for cardiovascular imaging and the real-time visualization of endovascular interventions. A key safety concern is the potential heating of metallic implants during MPI scans. This study evaluated the thermal behavior of various commercially available medical implants in a perfused human cadaver model. The measurements showed no detectable heating of the tested endovascular devices. A temperature increase of 0.04 K was observed in the tested femoral gamma nail. The study concludes that some commercial medical implants do not heat significantly in the used MPI scanner-setup under realistic conditions, indicating their safety for clinical use.
