Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Biomaterials

Background:

  • Magnetic resonance imaging (MRI) is increasingly used for diagnostics.
  • The temporal bone's anatomy necessitates evaluating MRI safety for patients with metallic middle ear implants.
  • Assessing implant displacement, temperature changes, and artifact generation is crucial for MRI safety and image quality.

Purpose of the Study:

  • To evaluate the safety of metallic middle ear implants during MRI scans.
  • To assess potential risks such as implant displacement and temperature increase.
  • To determine the impact of these implants on MRI image quality.

Main Methods:

  • Tested four stapes prostheses (titanium, gold, teflon/platinum, teflon/steel), a titanium total ossicular reconstruction prosthesis (TORP), and titanium/gold ventilation tubes.

  • Utilized a 1.5 Tesla MRI machine to assess displacement in petri dishes, suspended, and immersed conditions.
  • Recorded temperature changes using a pyrometer and evaluated MRI artifacts.

    • Main Results:

    • No implant displacement occurred in petri dishes or when suspended.
    • Teflon/platinum and teflon/steel pistons oriented longitudinally; teflon/steel piston showed minor movement towards the scanner.
    • No temperature increase was observed, and all implants produced minimal artifacts, allowing surrounding tissue evaluation.

    Conclusions:

    • Patients with the examined metallic middle ear implants can safely undergo MRI investigations.
    • The study confirms the safety of these implants regarding displacement and thermal effects.
    • MRI is a viable diagnostic tool for patients with these middle ear prostheses.
