    Coronary CTA is recommended as the first-line diagnostic strategy for suspected chronic coronary syndromes by ESC and ACC/AHA guidelines.

  • 2

    Conventional EID CT faces challenges in assessing coronary stents due to blooming artifacts and partial volume effects.

  • 3

    PCCT offers improved spatial resolution and lower electronic noise, enhancing image quality for coronary stent assessment.

  • 4

    The study aims to evaluate the in vivo diagnostic performance of ultrahigh-resolution PCCT compared to EID CT.

  • 5

    Eligibility for the study was restricted to patients with previous stent implantation undergoing coronary CTA.
