Photon-Counting Cardiac CT in Post-PCI Patients

Sponsor: Chinese PLA General Hospital

Summary

This study takes patients who have undergone percutaneous coronary intervention as the research subjects and employs a prospective observational cohort design, aiming to develop and validate a "one-stop" photon-counting computed tomography imaging framework. The one-stop PCCT protocol implies that multiple assessments are acquired through a single examination, including coronary CT angiography for stent and native artery evaluation, resting first-pass myocardial iodine distribution imaging, and delayed myocardial extracellular volume quantification, with cardiac cine imaging performed in a prespecified dose-controlled substudy.
