Myocardial viability assessment is of utmost importance in the assessment of patients with poor left ventricular function undergoing revascularisation therapies or cardiac transplantation. Cardiac positron emission tomography (PET) is widely regarded as a "gold" standard in myocardial viability assessment. We review the current data on this subject with respect to tracers and techniques, and prognostic information. The newer cardiac PET techniques in perfusion, hypoxia and neuronal imaging are also discussed, with mention of possible new applications of cardiac PET.
心肌活力评估在对左心室功能不佳且正在接受血运重建治疗或心脏移植的患者进行评估时至关重要。心脏正电子发射断层扫描（PET）被广泛视为心肌活力评估的“金”标准。我们回顾了关于该主题在示踪剂、技术以及预后信息方面的当前数据。还讨论了灌注、缺氧和神经成像方面更新的心脏PET技术，并提及了心脏PET可能的新应用。
