Coronary artery disease is the most common cause of mortality and morbidity around the globe. Assessment of myocardial perfusion to diagnose ischemia is commonly performed in symptomatic patients prior to referral for cardiac catheterization. Among other noninvasive imaging modalities, cardiac MRI (CMR) is emerging as a highly sensitive and specific test for myocardial ischemia and infarction. Resting perfusion on CMR is used to evaluate for microvascular obstruction, which is shown to predict adverse left ventricular remodeling and cardiac events after acute myocardial infarction. This article summarizes the current understanding of CMR perfusion.
冠状动脉疾病是全球范围内死亡和发病的最常见原因。在有症状的患者转诊进行心脏导管插入术之前,通常会进行心肌灌注评估以诊断缺血。在其他非侵入性成像方式中,心脏磁共振成像(CMR)正成为一种对心肌缺血和梗死高度敏感且特异的检查方法。CMR上的静息灌注用于评估微血管阻塞,微血管阻塞已被证明可预测急性心肌梗死后左心室不良重塑和心脏事件。本文总结了目前对CMR灌注的认识。
