Over the past years, the number of coronary computed tomography angiography (CTA) studies performed worldwide has been steadily increasing. Performing a coronary CTA study with appropriate protocols tailored to the individual patient and clinical question is mandatory to obtain an image quality that is diagnostic for the study purpose. This process can be considered the primary mainstay of each coronary CTA study. The secondary mainstay is represented by the correct analysis and interpretation of the acquired data, as well as reporting of the pertinent imaging findings to the referring physician. The latter process requires knowledge of the advantages and disadvantages of various post-processing methods. In addition, a standardized approach can be helpful to avoid false-positive and false-negative findings regarding the presence or absence of coronary artery disease. By implementing various radiation dose reduction techniques, care needs to be taken to keep the radiation dose of coronary CTA as low as reasonably achievable while maintaining the diagnostic capacity of the examination. This review describes a practical approach to the analysis and interpretation of coronary CTA data, including the standardized reporting of the relevant imaging findings to the referring physicians.
在过去的几年中，全球进行的冠状动脉计算机断层扫描血管造影（CTA）研究数量一直在稳步增加。为了获得对研究目的具有诊断价值的图像质量，必须使用针对个体患者和临床问题量身定制的适当协议进行冠状动脉 CTA 研究。这一过程可以被视为每个冠状动脉 CTA 研究的主要支柱。次要支柱是正确分析和解释所获得的数据，并将相关成像结果报告给转诊医生。这一过程需要了解各种后处理方法的优缺点。此外，采用标准化方法有助于避免在存在或不存在冠状动脉疾病方面出现假阳性和假阴性结果。通过实施各种辐射剂量降低技术，需要注意将冠状动脉 CTA 的辐射剂量保持在尽可能低的合理水平，同时保持检查的诊断能力。本综述描述了一种实用的冠状动脉 CTA 数据分析和解释方法，包括向转诊医生标准化报告相关成像结果。
