Abstract

The noninvasive detection of the presence and functional significance of coronary artery stenosis is important in the diagnosis, risk assessment, and management of patients with known or suspected coronary artery disease. Quantitative assessment of myocardial perfusion can provide an objective and reproducible estimate of myocardial ischemia and risk prediction. Positron emission tomography, cardiac magnetic resonance, and cardiac computed tomography perfusion are modalities capable of measuring myocardial blood flow and coronary flow reserve. In this review, we will discuss the technical aspects of quantitative myocardial perfusion imaging with positron emission tomography, cardiac magnetic resonance imaging, and computed tomography, and its emerging clinical applications.

摘要

非侵入性检测冠状动脉狭窄的存在及其功能意义对于已知或疑似冠状动脉疾病患者的诊断、风险评估和管理非常重要。心肌灌注的定量评估可以提供心肌缺血和风险预测的客观和可重复的估计。正电子发射断层扫描、心脏磁共振和心脏计算机断层灌注是能够测量心肌血流和冠状动脉血流储备的方式。在这篇综述中,我们将讨论正电子发射断层扫描、心脏磁共振成像和计算机断层扫描定量心肌灌注成像的技术方面及其新兴的临床应用。
