Abstract

Recent developments in cardiac magnetic resonance imaging (MRI) have led to tremendous breakthroughs in the imaging of acute myocardial ischaemia and infarction. Hardware and acquisition sequences have improved image quality while simplifying cardiac examinations. Cine-MRI allows for accurate time-resolved imaging of global and segmental left ventricular (LV) function with high spatial resolution. Dynamic multislice MRI of myocardial perfusion is now widely available allowing for the detection of microvascular obstruction after myocardial infarction (MI) or adding significant diagnostic value over usual clinical and biological markers after non ST elevation coronary syndromes. Direct high-resolution MRI of MI is well standardized with important clinical implications for the diagnosis of myocardial viability. In addition, stress cardiac MRI enables time-resolved analysis of myocardial perfusion under pharmacological stress, or accurate assessment of regional LV function during dobutamine cine-MRI for detection of myocardial ischaemia and/or viability. Non-invasive MR coronary angiography is beyond the scope of this article.
