    Photon-counting computed tomography (PCD-CT) offers improved dose efficiency and reduced image noise compared to energy-integrating detector (EID) systems.

  • 2

    Metal artifacts in CT imaging can obscure critical diagnoses, necessitating advanced techniques like iterative metal artifact reduction (iMAR) and virtual monoenergetic imaging (VMI).

  • 3

    The study evaluated the effectiveness of combining VMI and iMAR in a first-generation PCD-CT system for reducing metal artifacts from dental implants.

  • 4

    Fifty patients with dental implants were included in the study, which utilized a cadmium-telluride-based PCD-CT system for imaging.

  • 5

    Results indicated that the combination of VMI and iMAR significantly improved image quality and reduced metal artifacts in patients with dental implants.
