The diagnostic work-up for myocarditis largely depends on non-invasive imaging because of the low yield of endomyocardial biopsy. In addition, differentiation among possible impressions is essential because of its non-specific clinical presentations. This ambiguity has led to the predominant use of cardiac magnetic resonance imaging techniques in the management of myocarditis, particularly during the global pandemic. Despite the unique ability of F-18 fluorodeoxyglucose positron emission tomography to visualize and quantify active myocardial inflammation, which has been well established in cardiac sarcoidosis, its diagnostic contribution in non-sarcoidotic myocarditis remains uncertain. This article reviews the current evidence on the non-invasive imaging diagnosis of non-sarcoidotic myocarditis and discusses the potential role of F-18 fluorodeoxyglucose positron emission tomography as a clinically relevant imaging tool.
由于心内膜心肌活检的阳性率较低，心肌炎的诊断检查很大程度上依赖于非侵入性成像。此外，鉴于心肌炎临床表现不具特异性，区分可能的诊断结果至关重要。这种不确定性导致在心肌炎的管理中，尤其是在全球大流行期间，心脏磁共振成像技术得到了广泛应用。尽管F-18氟脱氧葡萄糖正电子发射断层扫描在可视化和量化活动性心肌炎症方面具有独特能力，这在心脏结节病中已得到充分证实，但其在非结节病性心肌炎中的诊断作用仍不确定。本文综述了非结节病性心肌炎非侵入性成像诊断的当前证据，并讨论了F-18氟脱氧葡萄糖正电子发射断层扫描作为一种临床相关成像工具的潜在作用。
