Diagnostic Performance of Extracellular Volume Native T1 and T2 Mapping versus Lake Louise Criteria by CMR for Detection of Acute Myocarditis: A Meta-Analysis

摘要

BackgroundThe Lake Louise Criteria (LLC) was established in 2009 and is the recommended cardiac magnetic resonance (CMR) imaging criterion for diagnosing patients with suspected myocarditis. Subsequently, newer parametric imaging techniques which can quantify T1, T2, and the extracellular volume (ECV) have been developed and may provide additional utility in the diagnosis of myocarditis. However, whether their diagnostic accuracy is superior to LLC remains unclear. In this meta-analysis, we compared the diagnostic performance of native T1, T2, ECV to LLC in diagnosing acute myocarditis.
