Coronary computed tomographic angiography (CCTA) is a viable alternative to catheter coronary angiography for several clinical indications, chiefly because it is fast and non-invasive. For effective clinical use of CCTA, various technical and patient factors should be considered. In this brief review article, we discuss the indication and contraindications for CCTA, technical requirements for CCTA including radiation dose, patient preparation principles, image post-processing, and pitfalls and artifacts of CCTA.
冠状动脉计算机断层扫描血管造影（CCTA）是一种可行的替代导管冠状动脉造影的方法，适用于多种临床指征，主要是因为它快速且无创。为了有效进行 CCTA 的临床应用，需要考虑多种技术和患者因素。在这篇简要综述中，我们讨论了 CCTA 的适应证和禁忌证、CCTA 的技术要求，包括辐射剂量、患者准备原则、图像后处理以及 CCTA 的潜在问题和伪影。
