Coronary Evaluation And Guided Lesion Exploration Using Photon-counting CT and Intracoronary Imaging Techniques

A dedicated cardiac UHR PCCT will be conducted within a maximum of 24 hours in ACS subjects and 72 hours in CCS subjects prior to the invasive CAG. Additionally, patients are also eligible for inclusion in case no PCCT is conducted prior to CAG, as long as no PCI is performed during the initial CAG. In these cases, the PCCT must be conducted within 24 hours for ACS patients and within 72 hours for CCS patients.
