    Photon-counting CT (PCCT) enhances cardiovascular imaging by providing high-quality cardiac examinations without compromising scan time or resolution.

  • 2

    Personalized iodine delivery rate (IDR) protocols aim to optimize vessel enhancement while minimizing total iodine dose in coronary CT angiography.

  • 3

    The study included a retrospective and prospective cohort to validate a personalized IDR formula and assess the impact of standardized injection rates.

  • 4

    A biphasic injection protocol was utilized, with varying iodine concentrations and rates based on patient-specific metrics to achieve optimal coronary enhancement.

  • 5

    The study's ultimate goal is to establish a validated injection protocol that ensures consistent coronary enhancement across diverse patient populations.
