PY - 2018 T2 - Color Atlas and Synopsis of Heart Failure AB - Cardiac magnetic resonance (CMR) imaging has become a powerful diagnostic tool in the assessment of cardiomyopathy. CMR not only provides a comprehensive evaluation of structure and function, but also allows for tissue characterization. CMR is the gold standard for quantification of cardiac volumes and function; it allows 3-dimensional visualization of the heart, as well as detailed flow evaluation with velocity encoded cine imaging. Tissue characterization has become the most exciting aspect of CMR in the field of heart failure (HF). The use of late gadolinium enhancement (LGE) allows for direct visualization of focal ischemic and nonischemic scar. Advances in T1 mapping now enable quantification of diffuse myocardial fibrosis by measuring the extent of interstitial expansion via extracellular volume (ECV) fraction. Further tissue characterization is performed with T2 mapping allowing for visualization of myocardial edema, while T2 star mapping directly quantifies myocardial iron content. The comprehensive nature of CMR not only yields high-quality diagnostic data, but also significant prognostic information, especially in patients with HF. This chapter will highlight the critical role of CMR in the assessment of cardiomyopathies.
