Role of cardiac magnetic resonance imaging in the diagnosis of nonischemic cardiomyopathies

Abstract

In recent decades, cardiac magnetic resonance imaging (CMR) has been established  as a valuable tool in the diagnosis of patients with or at risk of heart failure. With its ability to characterize tissue changes in the myocardium, CMR can provide detailed and clinically useful information about the type and severity of cardiac damage. The method is not only important for differentiation of ischemic from non-ischemic cardiomyopathy, but also contributes to the correct diagnosis of non-ischemic cardiomyopathy subtypes. It is also widely accepted as a reference standard for the quantification of myocardial mass, volumes and ejection fraction. The purpose of this article is to review the role of CMR in the diagnosis and treatment of non-ischemic cardiomyopathies.
