    Photon-counting computed tomography (PCCT) enhances malignant feature detection and diagnostic confidence in lung cancer patients.

  • 2

    PCCT reduces radiation exposure by 66% and iodine load by 27% compared to standard energy-integrating detector computed tomography.

  • 3

    At 0.4 mm resolution, PCCT detected significantly more malignant features than energy-integrating detector CT, with improved image quality.

  • 4

    Adverse reactions and contrast-induced acute kidney injury rates were lower in patients undergoing PCCT compared to EID CT.

  • 5

    The study's limitations include its single-center design and potential lack of generalizability due to the specific population studied.
