Abstract

Photon-counting CT (PCCT) represents a transformative advancement in cardiac imaging, addressing key limitations of conventional CT. This review synthesises current evidence to demonstrate how PCCT's superior spatial resolution, enhanced tissue characterisation and multienergy capabilities broaden the diagnostic potential of cardiac CT. Applications include the precise detection and quantification of coronary artery calcifications, evaluation of coronary plaque burden and composition, improved assessment of coronary stents, and comprehensive myocardial tissue characterisation and perfusion analysis. By offering high-quality spectral information and detailed tissue characterisation, PCCT provides a non-invasive alternative for assessing coronary artery disease and myocardial pathology, reducing the need for invasive coronary angiography and cardiac MRI. Despite ongoing challenges in technology and clinical implementation, PCCT has the potential to revolutionise cardiovascular diagnostics, optimise diagnostic workflows and enhance patient care through more accurate, streamlined and comprehensive assessments.

光子计数计算机断层扫描在心血管医学中的应用现状和未来。

光子计数CT （PCCT）代表了心脏成像的革命性进步，解决了传统CT的关键局限性。这篇综述综合了目前的证据来证明PCCT优越的空间分辨率，增强的组织特征和多能能力如何扩大心脏CT的诊断潜力。应用包括冠状动脉钙化的精确检测和定量，冠状动脉斑块负荷和组成的评估，改进冠状动脉支架的评估，以及全面的心肌组织表征和灌注分析。通过提供高质量的光谱信息和详细的组织特征，PCCT为评估冠状动脉疾病和心肌病理提供了一种非侵入性的替代方法，减少了对侵入性冠状动脉造影和心脏MRI的需求。尽管在技术和临床实施方面面临着持续的挑战，但PCCT有可能彻底改变心血管诊断，优化诊断工作流程，并通过更准确、更精简和更全面的评估来加强患者护理。
