Myocarditis is the inflammation of myocardial tissue.Cardiac imaging examinations can objectively reflect the histological characteristics and functional status of the heart in myocarditis.The electrocardiogram is widely used as a preliminary screening tool for myocarditis.Echocardiography is the first-line and most common imaging method for evaluating the cardiac structure and function of patients with suspected myocarditis because it can quickly and timely assess the myocardial damage and severity.Cardiac magnetic resonance(CMR)can accurately detect damage and edema in myocarditis,increasingly replacing endomyocardial biopsy(EMB)in the diagnosis of acute myocarditis.Radionuclide myocardial imaging can detect inflammatory infiltration and necrosis,as well as evaluate myocardial viability and perfusion,which is of high vaue in the diagnosis of myocarditis.The use of imaging examinations,combined with comprehe-nsive clinical analysis,plays an important role in the accurate diagnosis and treatment of myocarditis.
