Abstract

Purpose of review: This article summarizes findings seen in various cardiomyopathies on myocardial perfusion imaging (MPI) with positron emission tomography (PET).

Recent findings: MPI is the cornerstone for evaluation of coronary ischemia, and technological advancements have yielded improved imaging quality and reduction in radiation exposure, particularly with PET. Multi-specialty guidelines and appropriate use criteria provide guidance on utilization of PET MPI in various scenarios related to evaluation of chest pain, new onset cardiomyopathy, and other scenarios where coronary ischemia should be assessed. Various non-ischemic cardiomyopathies such as septal and apical hypertrophic cardiomyopathy, amyloidosis, sarcoidosis, takotsubo, and dilated cardiomyopathy have typical imaging findings on PET MPI and can be identified if these patterns are understood. It is essential to recognize specific imaging patterns in non-ischemic cardiomyopathies which may aide in diagnosis. Ultimately, multimodality imaging, including echocardiography and cardiac magnetic resonance, complement PET MPI in diagnosing and guiding treatment options for these conditions.

利用正电子发射断层扫描心肌灌注成像诊断非缺血性心肌病。

综述目的：本文总结了正电子发射断层扫描（PET）心肌灌注成像（MPI）在各种心肌病中的发现：MPI 是评估冠状动脉缺血的基石，技术的进步提高了成像质量，减少了辐射暴露，尤其是 PET。多专科指南和适当使用标准为 PET MPI 在评估胸痛、新发心肌病和其他需要评估冠状动脉缺血的各种情况下的使用提供了指导。各种非缺血性心肌病，如室间隔和心尖肥厚型心肌病、淀粉样变性、肉样瘤病、拓扑型心肌病和扩张型心肌病在 PET MPI 上都有典型的成像结果，如果了解这些模式，就可以进行识别。识别非缺血性心肌病的特殊成像模式至关重要，这有助于诊断。最终，包括超声心动图和心脏磁共振在内的多模态成像可辅助 PET MPI 诊断这些疾病并指导治疗方案。

期刊介绍： The aim of this journal is to provide timely perspectives from experts on current advances in cardiovascular medicine. We also seek to provide reviews that highlight the most important recently published papers selected from the wealth of available cardiovascular literature. We accomplish this aim by appointing key authorities in major subject areas across the discipline. Section editors select topics to be reviewed by leading experts who emphasize recent developments and highlight important papers published over the past year. An Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. We also provide commentaries from well-known figures in the field.
