The role of magnetic resonance imaging in the diagnosis of ischemic heart disease has great potential impact on patient management, because a number of aspects of ischemic heart disease can be evaluated in one imaging session. High resolution coronary magnetic resonance angiography is currently available, although several technical improvements are awaited to make the technique routinely applicable. A major advance will probably include the availability of magnetic resonance blood pool contrast agents to improve vessel visualization. Contrast media, in combination with either first pass or delayed myocardial scanning, will also play an important role in myocardial perfusion imaging. Functional magnetic resonance assessment of regional and global ventricular function is currently a well-established technique and is considered a new gold standard, which may impact on routine cardiology practice. This review summarizes some of the recent magnetic resonance developments for evaluating various aspects of ischemic heart disease, including magnetic resonance coronary angiography, flow imaging, and imaging of myocardial perfusion and function.
磁共振成像在缺血性心脏病诊断中的作用对患者管理具有巨大的潜在影响，因为在一次成像检查中就能评估缺血性心脏病的多个方面。目前已有高分辨率冠状动脉磁共振血管造影技术，不过仍需一些技术改进以使该技术能常规应用。一项重大进展可能包括可使用磁共振血池造影剂来改善血管显影。造影剂结合首过或延迟心肌扫描，在心肌灌注成像中也将发挥重要作用。目前，对局部和整体心室功能进行功能性磁共振评估是一项成熟的技术，被视为一种新的金标准，这可能会影响常规心脏病学实践。本文综述了近期在评估缺血性心脏病各个方面的一些磁共振成像进展，包括磁共振冠状动脉血管造影、血流成像以及心肌灌注和功能成像。
