Extracellular volume (ECV) fraction refers to the proportion of extracellular matrix in the whole myocardium. Elevated ECV values are observed in conditions such as myocardial infarction, cardiac amyloidosis, myocarditis, and hypertrophic cardiomyopathy. ECV mapping can assist in differentiating between these and other diseases, as well as providing prognostic information[1–5]. Cardiac magnetic resonance (CMR) imaging has been the non-invasive gold standard for ECV assessment due to its high acc…
