Imaging techniques play a vital role in evaluating myocardial damage in patients with myocardial infarction. Accurate evaluations of post-infarction function and scar can help identify high-risk patients and provide prognosis information, which contributes much to clinical practice. The assessment of myocardial damage mainly includes overall evaluations of ventricular function and remodeling and targeted characterization of myocardial infarction including infarct size, myocardial viability and microvascular obstruction. Echocardiography, cardiac magnetic resonance, CT and nuclear examinations are most common imaging techniques currently. This review is to evidence on applications of these modalities in evaluation of post-infarction myocardial damage and offer some helps to health workers.
