Overview

Safety measurements revealed no significant heating of medical implants during MPI in cadaver model, suggesting clinical applications may be feasible.

Key Points

  • No significant heating was observed in endovascular devices during magnetic particle imaging sessions, ensuring safety.
  • In vitro testing showed slight heating of 0.45 K in orthopedic prostheses with excitation frequency dependence.
  • Safety measurements were conducted using fiberoptic thermometers on metallic medical implants during MPI.
  • Results indicate that medical implants are likely safe for use in future clinical applications under realistic conditions.
