Abstract

Photon-counting computed tomography (PCCT) is an emerging technology that can potentially transform clinical CT imaging. After a brief description of the PCCT technology, this review summarizes its main advantages over conventional CT: improved spatial resolution, improved signal and contrast behavior, reduced electronic noise and artifacts, decreased radiation dose, and multi-energy capability with improved material discrimination. Moreover, by providing an overview of the existing literature, this review highlights how the PCCT benefits have been harnessed to enhance and broaden the diagnostic capabilities of CT for cardiovascular applications, including the detection of coronary artery calcifications, evaluation of coronary plaque extent and composition, evaluation of coronary stents, and assessment of myocardial tissue characteristics and perfusion.

摘要

光子计数计算机断层扫描（PCCT）是一项新兴技术，它有可能改变临床CT成像。在简要介绍PCCT技术之后，本综述总结了其相对于传统CT的主要优势：提高空间分辨率、改善信号和对比度表现、减少电子噪声和伪影、降低辐射剂量以及具备多能量能力且改善了物质辨别能力。此外，通过概述现有文献，本综述强调了如何利用PCCT的优势来增强和拓宽CT在心血管应用方面的诊断能力，包括冠状动脉钙化的检测、冠状动脉斑块范围和成分的评估、冠状动脉支架的评估以及心肌组织特征和灌注的评估。
