Compared with traditional invasive coronary angiography (ICA), coronary CT angiography (CCTA) has the advantages of being rapid, economical, and minimally invasive. The wide-detector CT, with its superior temporal resolution and robust three-dimensional reconstruction technology, thus enables CCTA in patients with high heart rates and arrhythmias, leading to a high potential for clinical application. This paper systematically summarizes wide-detector CT hardware configurations of various vendors routinely used for CCTA examinations and reviews the effects of patient heart rate and heart rate variability, scanning modality, reconstruction algorithms, tube voltage, and scanning field of view on image quality and radiation dose. In addition, novel technologies in the field of CT applied to CCTA examinations are also presented. Since this examination has a diagnostic accuracy that is highly consistent with ICA, it can be further used as a routine examination tool for coronary artery disease in clinical practice.
与传统的有创性冠状动脉造影（ICA）相比，冠状动脉 CT 血管造影（CCTA）具有快速、经济和微创的优点。宽探测器 CT 具有较高的时间分辨率和强大的三维重建技术，因此可以在心率高和心律失常的患者中进行 CCTA，具有很高的临床应用潜力。本文系统总结了常用于 CCTA 检查的各种供应商的宽探测器 CT 硬件配置，并回顾了患者心率和心率变异性、扫描方式、重建算法、管电压和扫描视野对图像质量和辐射剂量的影响。此外，还介绍了 CT 领域应用于 CCTA 检查的新技术。由于该检查与 ICA 的诊断准确性高度一致，因此可以进一步作为临床实践中冠心病的常规检查工具。
