Disclosing the cardiomyopathic substrate within the heart muscles in amyloidosis by cardiac magnetic resonance: diagnostic and prognostic implications

Abstract

The use of cardiac magnetic resonance (CMR) for accurate morphological assessment of cardiomyopathies is well described. CMR tissue characterization with late gadolinium enhancement and parametric mapping is highly promising in differentiating key etiologies of left ventricular hypertrophy, diagnosing cardiac involvement in systemic amyloidosis, detecting early disease, and tracking changes over time, as well as providing valuable prognostic information. This review focuses on the typical imaging findings in cardiac amyloidosis by CMR, highlighting its potentials with respect to traditional imaging techniques. Furthermore, the diagnostic and prognostic role of CMR parameters and the future perspectives related to the newest applications are addressed.
