Cardiac Magnetic Resonance Imaging for Myocardial Infarction Assessment of the Heart, Myocardium, and Coronary Vasculature
This non-invasive cardiac magnetic resonance imaging (MRI) exam leverages powerful magnetic fields to produce high-resolution, detailed images of the heart and its full cardiovascular network, including all four heart chambers, myocardial tissue, heart valves, coronary arteries, cardiac veins, and associated lymphatic vessels, with no exposure to ionizing radiation and no routine requirement for contrast agents for this specific myocardial infarction assessment protocol. It is clinically used to pinpoint areas of scarred or hypoperfused myocardial tissue caused by a prior heart attack, assess residual left and right ventricular function, evaluate for post-infarction complications including abnormal heart wall motion, ventricular thrombus, or ventricular aneurysm, and quantify blood flow through the coronary arteries and heart chambers without the need for invasive cardiac catheterization.
This non-invasive, radiation-free cardiac MRI exam uses magnetic fields to identify scarred myocardial tissue from prior myocardial infarctions, evaluate all components of the heart and its coronary vasculature, and assess cardiac function without invasive catheterization.
