Coronary Computed Tomography angiography (CCTA) gained a pivotal clinical role for excellent sensitivity in rule-out CAD, but has limited specificity for a tendency to overestimate stenoses and for the lack of information about their hemodynamic impact. Fractional Flow Reserve derived from CT (FFR-CT) and stress CT perfusion (CTP) have been recently proposed to complement CCTA in the non-invasive assessment of myocardial ischemia, increasing the specificity and avoiding unnecessary catheterization. However, on energy-integrating (EID)-CT, FFR-CT has suboptimal performance, while CTP is affected by high radiation exposure. Both these approaches may benefit by the introduction of the new Photon Counting Detector (PCD)-CT technology, but data completely lacks. Aim of the study is to assess the performance of PCD-CT in the identification of significant CAD combining CCTA with FFR-CT and spectral CTP.",[63,64,65,66],"FFR-CT","CT Angiography","CT Perfusion","Coronary Arterial Disease (CAD)",[63,68,65,66],"Coronary CT angiography","NOT_YET_RECRUITING","2026-04-15",{"date":72,"type":73},"2026-04-22","ACTUAL",{"date":75,"type":58},"2026-09-01",{"date":77,"type":58},"2029-09-01",{"name":5,"class":6},2]
