    Coronary CT angiography (CCTA) is recommended as the first-line test for assessing coronary artery disease in symptomatic patients.

  • 2

    Energy-integrating detector CTs may overestimate coronary stenosis due to limited spatial resolution and increased image noise.

  • 3

    Photon-counting detector CT technology offers improved spatial resolution and reduced blooming artifacts in patients with coronary calcification.

  • 4

    The study evaluated the diagnostic accuracy of dual-source photon-counting detector CT compared to energy-integrating detector CT.

  • 5

    A total of 143 patients underwent CCTA with photon-counting detector CT, while 109 patients were analyzed with energy-integrating detector CT.
