The Role of Cardiac MRI in Non- Ischemic Cardiomyopathy

Cardiac magnetic resonance (CMR) imaging has major rule in the diagnosis, assessment and prognosis of cardiomyopathies. Technologic advances in CMR imaging have resulted in images with high spatial and temporal resolution and excellent myocardial tissue characterization. CMR is a valuable technique for detection and assessment of the morphology and functional characteristics of the non-ischemic cardiomyopathy. It has acceptance the imaging modality that can provide additional information to echocardiography and angiography. CMR of left and right ventricular structure, function, tissue characterization with late gadolinium enhancement, T1 and T2 mapping and strain enable diagnosis and differentiation the etiology of non-ischemic cardiomyopathies.
A major role for cardiac MR imaging in cardiomyopathies is to identify myocardial scar for diagnostic and prognostic purposes. So Gadolinium based contrast media in CMR can depict myocardial edema, infiltration, and fibrosis. In addition, the presence and extent of LGE in cardiomyopathies are associated with adverse cardiovascular outcomes and poor responses to standard medical and interventional therapies. Thus, CMR has a major role to play in determining diagnosis and assessing prognosis for patients with non –ischemic cardiomyopathies. This presentation recommended cardiac MR imaging appearances of the different non- ischemic cardiomyopathies.
