myocardial contrast echocardiography
Also written as: MCE — Myocardial Contrast Echocardiography
An imaging technique using microbubble contrast agents to assess myocardial perfusion and viability.
Full Definition
Myocardial contrast echocardiography (MCE) is an advanced cardiac imaging modality that employs intravenous microbubble contrast agents to evaluate myocardial perfusion at the tissue level. The technique allows real-time assessment of coronary microvascular function and can detect areas of reduced perfusion that may not be apparent with standard echocardiography. MCE is particularly valuable in research settings for evaluating the effectiveness of reperfusion therapies, assessing myocardial viability, and detecting microvascular obstruction following acute myocardial infarction. The technology provides quantitative measurements of myocardial blood flow and can help differentiate between epicardial coronary artery disease and microvascular dysfunction. This imaging approach has shown promise in clinical trials as a surrogate endpoint for assessing therapeutic interventions.
Usage
Usage note: Specify the type of contrast agent used when reporting MCE results.
