最近的技术进步推动了混合放射性核素和CT心脏成像的发展。无创影像研究是诊断冠状动脉疾病（CAD）、分层风险和指导临床管理的可靠手段。心肌灌注显像是一种可靠的、广泛使用的无创方法，可用于评估已知或疑似CAD引起的缺血。心脏CT（冠状动脉钙评分和冠状动脉CT血管造影）已成为一种临床可靠的无创解剖成像检查，能够快速诊断或排除阻塞性CAD。解剖和功能模式都有各自的优点和缺点，并且可以通过提供综合的结构和生理信息来相互补充。正如我们下面讨论的，在选定的患者中，混合成像可能有助于更准确的诊断、风险分层和“一站式”管理。
Recent technological advances have fueled the growth in hybrid radionuclide and CT imaging of the heart. Noninvasive imaging studies are reliable means to diagnose coronary artery disease (CAD), stratify risk, and guide clinical management. Myocardial perfusion scintigraphy is a robust, widely available noninvasive modality for the evaluation of ischemia from known or suspected CAD. Cardiac CT (coronary artery calcium score and coronary CT angiography) has emerged as a clinically robust noninvasive anatomic imaging test, capable of rapidly diagnosing or excluding obstructive CAD. Both anatomic and functional modalities have strengths and weaknesses, and can complement each other by offering integrated structural and physiologic information. As we discuss below, in selected patients, hybrid imaging may facilitate more accurate diagnosis, risk stratification, and management in a “one-stop shop” setting.
