Evaluation of myocardial ischemia with cine-tagging and first-pass perfusion MRI

本研究的目的是利用标记心血管磁共振(CMR)定量测量左室心内膜下层和心外膜层的心肌应变，并探讨慢性缺血心肌跨壁收缩损害的程度。综上所述，3T标记MR分析可以无创性地量化左室壁变形的程度，并显示静息状态下慢性缺血心肌心内膜下应变的主要损害。

The purpose of this study was to quantify myocardial strain on the subendocardial and epicardial layers of the left ventricle (LV) using tagged cardiovascular magnetic resonance (CMR) and to investigate the transmural degree of contractile impairment in the chronic ischemic myocardium. In conclusion, analysis of 3T tagged MR can non-invasively quantify the transmural degree of left ventricular deformation and demonstrate predominate impairment of subendocardial strain in the chronic ischemic myocardium at rest.
