cardiac magnetic resonance imaging, myocardial viability, late gadolinium enhancement, coronary artery disease, left ventricular dysfunctionAbstract
Cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) is an advanced technique for assessing myocardial viability, essential for decision-making regarding revascularization in patients with coronary artery disease and left ventricular dysfunction. CMR provides high-resolution images without ionizing radiation, making it safe and repeatable. This article reviews the evolution of imaging techniques for assessing myocardial viability, focusing on CMR and its ability to identify viable myocardial tissue. The fundamentals of CMR, the importance of gadolinium as a contrast agent, and the criteria for fibrosis transmurality to determine myocardial viability are discussed. Additionally, key studies demonstrating the precision and clinical relevance of CMR in this context are highlighted.
