Cardiomyopathies are myocardial disorders that may result in ventricular dysfunction and can progress to heart failure. They are classified into a number of morphological and functional phenotypes that can be caused by genetic and non-genetic mechanisms. Non-invasive imaging plays a major role in the assessment of patients with heart failure and the identification of an underlying cardiomyopathy. Non-invasive imaging modalities can determine whether abnormalities are present in the myocardium, endocardium, or pericardium. Echocardiography is the most common imaging technique used for the initial diagnosis and management of cardiomyopathy; however, other imaging modalities, including cardiac magnetic resonance imaging (CMR), and cardiac computed tomography, may play an important role depending on the underlying etiology of the cardiomyopathy. CMR has emerged as a useful non-invasive imaging tool in the investigation of patients suffering from cardiomyopathy. CMR sequences have high spatial and temporal resolution image acquisition and become a gold standard non-invasive imaging modality for many cardiomyopathies. The acquisition of high-resolution images in any selected plane overcomes the limitations due to patient's body habitus and suboptimal acoustic windows. Furthermore, lack of ionizing radiation is a large advantage for the clinical follow-up of patients. The use of late gadolinium-enhanced sequences has had an important impact on the ability to characterize the myocardium. The pattern of myocardial fibrosis seen on late gadoliniumenhanced images is a major strength of CMR in helping the differential diagnosis of the underlying etiology of a cardiomyopathy. This presentation focuses on the classification of cardiomyopathies and basic CMR sequences used in evaluating different types of cardiomyopathies.
