Cardiovascular compute tomography (CT) is now a robust tool for the evaluation of coronary artery atherosclerosis and stenosis. A number of single-center studies, and now multicenter trials, have shown that the diagnostic accuracy of this tool compares favorably with the reference standard of conventional coronary angiography. Of course, CT angiography does not allow for the assessment of the functional significance of a given coronary lesion. However, recent reports have shown that myocardial perfusion imaging is possible with CT, opening up the possibility of providing a comprehensive evaluation of both coronary anatomy and physiology with one examination. This article reviews the principles, technical considerations, and the potential of stress myocardial perfusion imaging with CT.
心血管计算机断层扫描（CT）现在是评估冠状动脉粥样硬化和狭窄的强大工具。许多单中心研究，现在是多中心试验，已经表明该工具的诊断准确性可与传统冠状动脉造影的参考标准相媲美。当然，CT 血管造影不能评估给定冠状动脉病变的功能意义。然而，最近的报告表明，CT 可以进行心肌灌注成像，这为一次检查同时提供冠状动脉解剖和生理学的全面评估提供了可能性。本文回顾了 CT 应激心肌灌注成像的原理、技术考虑因素和潜力。
