The value of cardiovascular magnetic resonance for diagnosis of viral myocarditis / 国际儿科学杂志

ABSTRACT

Endocardial myocardial biopsy is the gold standard in the diagnosis of viral myocarditis.However,the limitations of sampling to the low sensitivity,and invasive inspection methods limit its clinical application.The traditional diagnostic tool electrocardiography,laboratory values and echocardiography are lack of specificity.Thus,a non-invasive diagnostic approach with high sensitivity is in need.Cardiovascular magnetic resonance(CMR) can evaluate the function of the heart parameters,such as left ventricular function and regional wall motion,and various CMR imagings including T2-weighted imaging,and early- and late-contrast enhanced T1-weighted imaging can evaluate the hyperemia,oedema and necrosis of myocardial inflammation histological character.CMR provides a scientific basis for the diagnosis of viral myocarditis in clinical.
