Cardiomyopathy refers to abnormal conditions of the cardiac muscles. Cardiomyopathies are a significant cause of mortality and morbidity caused due to cardiovascular pathologies. Dilated cardiomyopathy is the most common type of cardiomyopathy. Cardiac magnetic resonance imaging is an excellent modality for diagnosis and evaluation of cardiomyopathies. Non ischaemic cardiomyopathy is a type of cardiomyopathy which has varied etiologies, including and not limited to genetic, inflammatory conditions, auto-immune diseases, stress, infiltrative disorders, drug toxicity, granulomatous diseases and storage disorders. Hence role of cardiac magnetic resonance imaging is important in the diagnostic and research indications in cardiology. Cardiac MRI is a powerful tool in this regard owing to its multifaceted assessment of ventricular structure and myocardial physiology, in matching arbitrary scan planes. Cardiac MRI is routinely performed in experienced centers to complement echocardiography in assessing new cardiomyopathies. It is not only accurate but also highly reproducible. We present a case series depicting cardiac magnetic resonance imaging appearance of non ischaemic dilated cardiomyopathies which presented to our hospital.
