Synopsis

Keywords: Cardiomyopathy, Myocardium, Late gadolinium enhancementThis study investigated the advantages and potential disadvantages of the MOCO-LGE sequence. The results showed that MOCO-LGE can effectively improve the image quality compared to BH-LGE. Meanwhile, the MOCO-LGE images could overestimate epicardial hyperenhancement and pericardial effusion, which might lead to overdiagnosis of myocarditis in clinical work. The study indicates that further refinement of this useful sequence may be needed.
